The equilibrium constant for the reaction
`H_(2)(g)+S(s) hArr H_(2)S(g)`
is `18.5` at `925 K` and `9.25` at `1000 K`, respectively. Calculate the enthalpy of the reaction.

Text Solution

AI Generated Solution

To calculate the enthalpy of the reaction given the equilibrium constants at two different temperatures, we can use the van 't Hoff equation, which relates the change in the equilibrium constant (K) with temperature (T) to the enthalpy change (ΔH) of the reaction. ### Step-by-Step Solution: 1. **Identify the given values:** - Equilibrium constant at T1 (K1) = 18.5 at T1 = 925 K - Equilibrium constant at T2 (K2) = 9.25 at T2 = 1000 K ...
