The incorrect match in the following is:

Options

  1. AΔ G 0 < 0 , K > 1
  2. BΔ G 0 > 0 , K < 1
  3. CΔ G 0 = 0 , K = 1
  4. DΔ G 0 < 0 , K < 1

Correct answer

D. Δ G 0 < 0 , K < 1

Step-by-step solution

We know that &#916; G &#176; = - R T l n K &#916; G &#176; = - 2.303 &#160; R T log &#8289; K so for k = 1 , log &#8289; K = 0 hence &#916; G &#176; = 0 &#160; ; for k &#62; 1 , log &#8289; K &#62; 0 &#160; &#916; G &#176; = - v e for k &#60; 1 , log &#8289; K &#60; 0 &#916; G &#176; &#62; 0
