Question

Because there are more gas molecules on the reactants side of the reaction, when pressure is increased, the position of equilibrium shifts toward the side with _________ molecules to _______ the pressure.

a) fewer, decrease
b) more, decrease
c) fewer, increase
d) more, increase

Answer 1

According to Le Chatelier's principle, increasing pressure causes the equilibrium to shift to the side with fewer moles of gas.

Step-by-step explanation:

According to Le Chatelier's principle, if pressure is increased, then the equilibrium shifts to the side with the fewer number of moles of gas. This particular reaction shows a total of 4 mol of gas as reactants and 2 mol of gas as products, so the reaction shifts toward the products side.
