The value of K_(p) for the water gas reaction, CO +H_(2)O hArr CO_(2)

1.	The value of K_(p) for the water gas reaction, CO +H_(2)O hArr CO_(2) +H_(2)is 1.06 xx 10^(5) at 25^(@)C . Calculate the standard free energy change for the reaction at 25^(@)C.
Answer» Solution :`Delta_(r)G^(@) =- 2.303 rt LOG K = - 2.303 xx 8.314 xx 298 xx log ( 1.06 xx 10^(5))`
