Question

.For the following hypothetical reaction, the equilibrium constant(Kc) value is given as: A ⇌ B ; Kc = 2.0 The equilibrium constant (K’c) for the reaction B ⇌ A is

Answer 1

Dear student,
for the reaction , A $\stackrel{}{\rightleftharpoons }$ B , K = $\frac{\left[B\right]}{\left[A\right]}$ = 2.0 ....... ( 1)
And for the reaction , B $\stackrel{}{\rightleftharpoons }$ A , K ^' = $\frac{\left[A\right]}{\left[B\right]}$ ......... (2 )
From eq ( 1) and (2),
K" = 1 / K = 1/2 = 0.5
