Question

In an equilibrium reaction, for which $\Delta G^o=0$, the equilibrium constant $K$ should be equal to:

• A. Zero
• B. $10$
• C. $1$
• D. $2$

Answer 1

Answer: (C)

$1$

In an equilibrium reaction, for which $\Delta G^o=0$, the equilibrium constant $K$ should be equal to 1.
$\Delta G^o=-RTlnK$
$0=-RTlnK$
$lnK=0$
$K=1$
