Question

Suppose that the gas-phase reaction A B and B A are both elementary processes with rate constants of 4.91e-04 s-1 and 5.32e-03 s-1, respectively. Figure out the value of the equilibrium constant, KP, for the equilibrium A(g) B(g), and figure out which of the two substances, A or B develops higher partial pressure at equilibrium. Use this information to pick the choice from below which is correct. a) KP = 1.08e+01, and A(g) develops higher partial presssure. b) KP = 4.83e-03, and A(g) develops higher partial presssure. c) KP = 9.23e-02, and A(g) develops higher partial presssure. d) KP = 4.83e-03, and B(g) develops higher partial presssure. e) KP = 1.08e+01, and B(g) develops higher partial presssure.
