Consider again the gas phase reaction 2A → P in which the product, P is formed when two A molecules collide. Knowing that the equilibrium constant of this reaction is K = 1.0, and that the initial pressure of A was 1 atm, what change in the gas pressure in the reaction chamber do you expect?
a) The pressure will stay the same.
b) The pressure will increase.
c) The pressure will decrease.
d) Since K = 1.0, the total pressure of all gasses will be 1 atm.
e) Since K = 1.0, the pressure of all gasses will be 1 atm and thus the p(total) will be 3 atm.
