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

Answer 1

Answer:

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

Answer 2

Answer: 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.

Gases, fluids, and other solids in contact with a moving object will produce ____ due to friction.

Answers

Gases, fluids, and other solids in contact with a moving object will produce heat due to friction. The contact between molecules or atoms present in gases, fluids, and other solids creates energy and it may be in the form of heat.

The answer is: Heat flow

Which of the following is considered to be a dangerous procedure in the laboratory setting? a. Pouring all liquids, especially acids and bases, over the sink
b. Wearing goggles
c. Pushing glass tubing, thermometers, or glass thistle tubes through a rubber cork
d. Pointing the mouth of a test tube that is being heated away from you and others
e. Knowing where the fire extinguisher and eyewash stations are located

Answers

The answer is (A) , because all other options are safety precautions, not dangerous.

I think it's c because a is good as it won't cause spills on the floor, b you must do for eye safety d) is also for safety so chemicals don't burn or spit at you And e is needed incase a fire occurs or something is in your eye and immediately needs washing out therefore c is the only one which could be a danger

1 Iron can be extracted from iron(III) oxide using carbon, shown by the equation below:Fe²O³ + C -> Fe + CO
Balance the equation and state which substance is oxidised and which is reduced

Answers

Explanation:

To balance the chemical equation for the extraction of iron from iron(III) oxide using carbon, you need to ensure that the same number of each type of atom appears on both sides of the equation. Here's the balanced equation:

2Fe₂O₃ + 3C -> 4Fe + 3CO

Now, let's determine which substance is oxidized and which is reduced:

1. Iron (Fe) undergoes a change in oxidation state from +3 in iron(III) oxide (Fe₂O₃) to 0 in elemental iron (Fe). It is reduced because it gains electrons, going from a higher positive oxidation state to zero.

2. Carbon (C) in carbon (C) undergoes a change in oxidation state from 0 to +2 in carbon monoxide (CO). Carbon is oxidized because it loses electrons and goes from an oxidation state of 0 to +2.

So, in this chemical reaction:

- Iron is reduced (it gains electrons).

- Carbon is oxidized (it loses electrons).
