Answer to Question #330683 in General Chemistry for Yes

Question

The equilibrium constant, K_c, for the following reaction is 1.31×10^-2 at 700 K.

NH₄I(s) NH₃(g) + HI(g)

Calculate K_c at this temperature for the following reaction:

NH₃(g) + HI(g) NH₄I(s)

K_c = 

Answer 1

NH₄I(s) = NH₃(g) + HI(g), K_c = 1.31×10^-2

NH₃(g) + HI(g) = NH₄I(s), K_c' = 1/K_c = 1 / 1.31×10^-2 = 76.34
