Answer 1

Answer:

The equilibrium expression written for a reaction written in the reverse direction is the reciprocal of the one for the forward reaction.

K' = 1/K

K' is the constant for the reverse reaction and K is that of the forward reaction.

Step-by-step explanation:

What is the value of the equilibrium constant for the reaction 2 NO2(g) double arrows N2O4(g) at 100o C?

N2O4(g) double arrows 2 NO2(g) Kc = 0.212 @ 100oC?

The desired reaction is the reverse of the reaction for which the Kc is known. The equilibrium expression is the reciprocal of that given.
