Problem

The equilibrium constant for the gaseous reaction A(g)+B(g)⇌C(g)\text{A}(g) + \text{B}(g) \rightleftharpoons \text{C}(g) is Kc=4.0K_c = 4.0 at a certain temperature. A chemist instead writes the reaction as 2C(g)⇌2A(g)+2B(g)2\text{C}(g) \rightleftharpoons 2\text{A}(g) + 2\text{B}(g). Which of the following correctly relates the new equilibrium constant Kc′K_c' to the original constant KcK_c? a) Kc2K_c^{2} b) 1Kc\dfrac{1}{K_c} c) 1Kc2\dfrac{1}{K_c^{2}} d) 1Kc\dfrac{1}{\sqrt{K_c}}
