The value of equilibrium constant K_p for the reaction CO(g)+H_2O(g) leftrightarrow CO_2(g)+H_2(g)is 1.06 times 10^5at 25^@C Calculate standard free energy change of the reaction at the same temperature.

Answer»

Solution :`DELTAG^@=-2.303RT log_10K_p`
`=-2.303 times 8.314 times 298 times LOG (1.06 times 10^5)`
`=-2.303 times 8.314 times 298 times 5.0253`
`=-2867.3 Joules`
OR=-28.673 K J
