Ncert Exercises & Solutions

Match the standard free energy of the reaction with the corresponding equilibrium constant.

Codes:

Hint:

∆ G^{⊝} = - RT

\ln

K

As we know that,

∆ G^{⊝} = - RT

\ln

K

A. If

∆ G^{⊝} > 0

i.e.,

∆ G °

is positive, then ln K is negative i.e., K<1

B. If

∆ G^{⊝} < 0

, i.e.,

∆ G °

is negative then ln K is positive i.e., K>1

C. If

∆ G^{⊝} = 0

, ln K=0, i.e., K=1.
