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