Problem

Consider the following reaction at equilibrium. What effect will decreasing the temperature have on the system?

CO2(g) + 2 H2O(l) ⇋ CH4(g) + 2 O2(g)    ΔH° = +890 kJ

A) The reaction will shift to the left in the direction of reactants.

B) The equilibrium constant will decrease. 

C) The equilibrium constant will increase.

D) The reaction will shift to the right in the direction of products.

E) No effect will be observed.
