The value of the equilibrium constant for the combination of nitrogen and oxygen to make NO is 2 x 10-9. What does this tell you about the concentrations of materials in the equilibrium mixture?

Answers

Answer: The reaction must proceed in the reverse direction.

Explanation:

$K_p$ is the constant of a certain reaction at equilibrium while $Q_p$ is the quotient of activities of products and reactants at any stage other than equilibrium of a reaction.

For the given chemical reaction:

$N_2(g)+O_2(g)\rightleftharpoons 2NO(g)$

The expression of $K_p$ for above equation follows:

$K_p=((p_(NO))^2)/(p_(N_2)* p_(O_2))$

We are given:

$K_p=2* 10^(-9)$

There are 3 conditions:

When $K_(p)>1$ ; the reaction is product favored.

When $K_(p)<1$ ; the reaction is reactant favored.

When $K_(p)=1$ ; the reaction is in equilibrium.

As, $K_p<1$ , the reaction will be favoring reactant side or the reaction must proceed in the reverse direction.

Hence, the reaction must proceed in the reverse direction.

When farmers irrigate their crops, as much as 60 to 70 percent of the water _____. is ruined by pests, such as rabbits that are around the crops never reaches the crop is taken up by the plant is already contaminated by lead pipes

Answers

Answer:

Option (2)

Explanation:

The water in most of the region is generally pumped out of the ground for the purpose of irrigation. This rate of pumping is much higher than the rate of replenishment. The over-pumping of water leads to the lowering of the water table

About 60 to 70% of the water that is used for irrigation purposes does not reach the crop. It is because the water most of the time gets percolated down into the deeper zones. In addition to this, the water also leaks through the fractures that are associated with the canals and increasing rate of evaporation.

Thus, the correct answer is option (2).

Answer:b never reaches the crop hopefully helps

Which statement best describes the conductivity of weak electrolytes, such as weak acids and bases?A) Weak electrolytes do not dissolve in water and can not conduct electricity.
B) Weak electrolytes dissolve and partially dissociate in water providing charged ions to conduct electricity.
C) Weak electrolytes dissolve and completely dissociate in water providing charged ions to conduct electricity.
D) Weak electrolytes dissolve and does not dissociate in water providing no charged ions to conduct electricity.

Answers

Answer: B) Weak electrolytes dissolve and partially dissociate in water providing charged ions to conduct electricity.

Explanation: Weak electrolytes are those substances which do not dissociate completely when dissolved in water. They dissociate but then associate back and thus their dissociation is shown by an equilibrium sign. Example: $CH_3COOH$

$CH_3COOH\rightarrow CH_3COO^-+H^+$

The charged species formed helps in the conduction of electricity.

Strong electrolytes are those substances which dissociate completely when dissolved in water. Their dissociation is shown by a forward arrow. Example: $NaOH$

$NaOH\rightarrow Na^++OH^-$

The charged species formed helps in the conduction of electricity.

B. Weak electrolytes are weak because they only partially dissociate into ions in water.

Several steps are involved in the industrial production of sulfuric acid. One step involves the oxidation of sulfur dioxide gas to form sulfur trioxide gas. A catalyst is used to increase the rate of production of sulfur trioxide gas. In a rigid cylinder with a movable piston, this reaction reaches equilibrium, as represented by the equation below.2SO2(g) + O2(g) <==> 2SO3(g) + 392 kJ
Explain, in terms of collision theory, why increasing the pressure of the gases in the cylinder increases the rate of the forward reaction.
Determine the amount of heat released by the production of 1.0 mole of SO3(g).
State, in terms of the concentration of SO3(g) , what occurs when more O2(g) is added to the reaction at equilibrium.

Answers

Increasing the pressure will mean that these particles will collide more frequently to yield the products hence driving the forward reaction.

What is the collision theory?

According to the collsion theory, reaction occurs as a result of collision between reactants in a system. Now we have the reaction; 2SO2(g) + O2(g) <==> 2SO3(g) + 392 kJ.

We can see that there are more particles on the left hand side than on the right hand side. Increasing the pressure will mean that these particles will collide more frequently to yield the products hence driving the forward reaction.

Now;

2 moles of SO3(g) produces 392 kJ of heat

1 mole of SO3(g) produces 1 mole * 392 kJ /2 moles

= 196 kJ

Increasing the pressure of the gas increases the intermolecuar forces of attraction between the molecules because the distance between the molecules are being reduced by the action of the piston.
