See Question 4 (attached).
The answer is A, but why is it not B or D?
What's the rule here or the method to work this out?
Initially, I thought of using Surr = -H/T and that an increase in temperature decreases Surr entropy - but I don't know how to use this to help answer this question.
It says that a higher temperature moves the equilibrium to the side of products (RHS), so the reaction must be exothermic?
Help appreciated - thank you
