HCI(g) can react with methanol vapor, CH;OH(g), to produce CH;CI(g), as represented by the following equation. CH;OH(g) + HCI(g) 2 CH;CI(g) + H2O(g) K, = 4.7x 10° at 400 K CH,OH(g) and HC(g) are combined in a 10.00 L sealed reaction vessel and allowed to reach equilibrium at 400 K. The initial partial pressure of CHOH(g) in the vessel is 0.250 atm and that of HCI(g) is 0.600 atm. (i) Does the total pressure in the vessel increase, decrease, or remain the same as equilibrium is approached? Justify your answer in terms of the reaction stoichiometry.

HC(g) can react with methanol vapor, CH;OH(8), to produce CH;CI(g), as represented by the following equation. CH;OH(g) + HCI(g) 2 CH;CI(g) + H2O(g) K, = 4.7 x 10° at 400 K CH,OH(g) and HCI(g) are combined in a 10.00 L sealed reaction vessel and allowed to reach equilibrium at 400 K. The initial partial pressure of CH,OH(8) in the vessel is 0.250 atm and that of HCI(g) is 0.600 atm. (i) Does the total pressure in the vessel increase, decrease, or remain the same as equilibrium is approached? Justify your answer in terms of the reaction stoichiometry.
