D. increase the moles of gas. (b) ), Doubling the initial pressure, at constant temperature under which 1000 mL of a gas was confined causes the volume of the gas to A. When there is a decrease in volume, the equilibrium will shift to favor the direction that produces fewer moles of gas. The pressure on a gas at -73 degrees C is doubled, but its volume is held at constant.
