A change in temperature of the equilibrium system below increases the value of the equilibrium constant. The new state of equilibrium was established by a shift ________.

Question

CO(g) + 2H2(g) ⇔ CH3OH(g) + 91 kJ

a) to the left due to a temperature increase
b) to the left due to a temperature decrease
c) to the right due to a temperature increase
d) to the right due to a temperature decrease
e) to the left and then to the right due to a temperature increase

Answer 1

c) to the right due to a temperature increase

Answer 2

are you sure?

Answer 3

I apologize for the previous incorrect response.

In the given equation, the forward reaction is exothermic, as indicated by the release of 91 kJ of heat. According to Le Chatelier's principle, increasing the temperature of an exothermic reaction will favor the reverse reaction in order to absorb the excess heat and decrease the temperature. Therefore, the equilibrium will shift to the left.

Therefore, the correct answer is:
b) to the left due to a temperature increase.

Answer 4

What is the correct answer?

Answer 5

Apologies for the confusion. The correct answer is:

b) to the left due to a temperature increase.
