Consider the following chemical equilibrium:

Question

SO3(g) --> SO2(g) + 1/2 O2(g) and Delta H = 98.9J
a. Predict weather the forward or reverse reaction will occur when the equilibrium is disturbed by:
i. adding oxygen gas
ii. compressing the system at constant temperature
iii. adding argon gas
iv. removing sulfur dioxide gas
v. decreasing the temperature

b. Which of the above (i-v) will decrease the value of K?

Answer 1

All of this has to do with Le Chatlier's Principle. Tell us what you don't understand about the problem. We can help you through it but there is no point in telling you what you already know.
