Answer
a) Kp = 5.3 x 10^-3
b) Kp = 2.8 x 10^-5
c) Kp = 187
Work Step by Step
a) Since the reaction has been reversed and divided by 2:
Kp = 1/\sqrt 1.3x10^4 = 5.3 x 10^-3
b) Since the reaction has been reversed
Kp= 1/ 3.5x10^4 = 2.8 x 10^-5
c) SInce the coefficients of the reaction have been divided by 2
Kp = \sqrt 3.5x10^4 = 187
