Calculate the value of equilibrium constant of the reaction at \text{22}{\text{7}^{o}C , if the ΔGo\Delta G^{o} for the reaction X+Y⇌ZX + Y ⇌ Z is - 4.606 kcal. (R=2.0cal.mol−1K−1)( R = \text{2.0}cal. mol^{- 1}K^{- 1} )

Options

  1. A100
  2. B10
  3. C2
  4. D0.01

Correct answer

A. 100

Step-by-step solution

ΔGo=−2.303RT\logK\Delta G^{o} = - \text{2.303}RT\text\logK

−4.606=−2.303×0.002×500\logK- \text{4.606} = - \text{2.303} \times \text{0.002} \times \text{500}\text\logK

\logK=2,K=100\text\logK = 2, K = \text{100}.
