Use LeChatelier's principle to predict the effect, if any, of increasing the temperature of the equilibrium system, described below, in a closed container. Select the single best answer.
C(s) + 2 H2(g) ? CH4(g) + 18 kcal
Choose one of the following:
1) Equilibrium shifts right favoring products
2) No effect
3) Equilibrium shifts left favoring reactants
