For the water gas reaction,
`C(s) +H_(2)O(g) hArr CO(g)+H_(2)(g)`
the standard Gobbs free energy of reaction (at `1000K)` is `-8.1 kJ mol^(-1)`. Calculate its equilibrium constant.

Explanation

To calculate the equilibrium constant (K) for the water gas reaction given the standard Gibbs free energy change (ΔG°) at a specific temperature, we can follow these steps:

### Step 1: Write down the given data
- The reaction is:
\[ C(s) + H_2O(g) \rightleftharpoons CO(g) + H_2(g) \]
- Standard Gibbs free energy change (ΔG°) at 1000 K is given as:
