For the reaction below, describe the temperature and pressure conditions that would produce the highest yield of the forward reaction. Explain your answer in terms of Le Châtelier's principle.

Answers

Answer 1

Answer: The correct answer for the question that is being presented above is this one: "CO(g) + 2H2 (g) <---> CH3OH (g) and that the reaction is exothermic (the delta H value is negative). The reaction is exothermic, so lowering the temperature will shift the equilibrium toward the right. Since the reaction uses 3 moles of gas to form 1 mole of gas, increasing the pressure will shift the reaction toward the right. So, low temperature and high pressure will produce the highest yield. Le Chatelier's principle states that when a system at equilibrium is disturbed, the system responds in such a way to minimize the disturbance."

What is the correct way to solve a Maths problem ?

Determine what the question is asking. Write down the relevant information in simple statements. Assign symbols to unknown values that need to be found. Determine how the statements relate to each other mathematically.

To find the answer we can set up an equation : 3 (x) (d)

x = number of cans each dog eats

d = the number of days in a week.

Thus,

Number of Cans to purchase = 3 (2) (7)=42

Therefore, Sam would have to purchase 42 cans of dog food each week.

Equal amounts of ethanol and water are mixed at room temperature and at 101.3 kPa. Which process is used to separate the ethanol from the mixture?

Answers

Answer:

The process is known as fractional distillation

Explanation:

In order to separate the water from the ethanol at mixed room temperature with pressie of 1013 Kpa. The technique relies on the differential boiling points of the vapors that form a mixture above the flasks.

Thus the lower boiling points will lead to vaporize and rise through the column. Thus the remaining solution will bet concentrated and the amount of solvent it will decrease and substance with the lowest boiling point or room temperature will be collected first.

The answer is (1) distillation. Because the ethanol and water will mix well to form a solution
