For the reversible reaction, A(s)+B(g) (g)+D(g), G^ =-350 ~kJ , which one of the following statements is true?

Options

  1. AThe reaction is thermodynamically non-feasible
  2. BThe entropy change is negative
  3. CEquilibrium constant is greater than one
  4. DThe reaction should be instantaneous

Correct answer

C. Equilibrium constant is greater than one

Step-by-step solution

A(s)+B(g) C(g)+D(g), G^ =-350 ~kJ Relationship between G^ and equilibrium constant is G^ =-2.303 R T K_ p When K_ p >1 ; G^ is negative.
