Chapter 15, Problem 71E

Coal, which is primarily carbon, can be converted to natural gas, primarily CH₄, by the exothermic reaction:

$\text{C}\left(\text{s}\right)+\text{2H2}\left(\text{g}\right)\rightleftharpoons {\text{CH}}_{\text{4}}\left(\text{g}\right)$

Which disturbance favors CH₄ at equilibrium?

a. adding more C to the reaction mixture
b. adding more H₂ to the reaction mixture
c. raising the temperature of the reaction mixture
d. lowering the volume of the reaction mixture
e. adding a catalyst to the reaction mixture
f. adding neon gas to the reaction mixture
