Write the expression for the equilibrium constant, `K_(c)` for each of the following reactions: `2Cu(NO_(3))_(2)(s) hArr 2CuO(s)+4NO_(2)(g) +O_(2)(g)`

Text Solution

Verified by Experts

`K_(c)=[NO_(2)]^(4)[O_(2)][As" "Cu(NO_(3))_(2) and CuO` are pure solids, their molar concentration terms do not appear in the equiloibrium constant expression].
