which will not appear in the equilibrium constant expression for the reaction below?\nh₂o(g) + c(s)⇌h₂(g) + co(g)\nh₂o\nc\nh₂\nco

Answer

Explanation:

Step1: Recall equilibrium constant rules

The equilibrium constant ($K_c$) expression for a reaction $aA + bB \rightleftharpoons cC + dD$ is $K_c=\frac{[C]^c[D]^d}{[A]^a[B]^b}$, where only gaseous and aqueous species are included. Solids and pure liquids are omitted.

Step2: Analyze reaction species

In the reaction $H_2O(g)+C(s)\rightleftharpoons H_2(g) + CO(g)$, $H_2O$, $H_2$ and $CO$ are gases. Carbon ($C$) is a solid.
