Standard free energy change of a reaction is +150 kJ mol^(-1). Calculate K_(p) at 30^(@)C.

Answer»

Solution :`DELTA G^(@) = -2.303 RT log_(10) K_(p)`
`log_(10) K_(p) = (Delta G^(@))/(-2.303 xx R xx T)`
`log_(K_(p)) = (150000)/(-2.303 xx 8.314 xx 300)`
`log K_(p) = -26.1136`
`K_(p) = "ANTILOG"- 26.1136`
`K_(p) = "antilog" BAR(27).8864`
`= 7.698 xx 10^(-27)`
