If ΔGT=nRTlnV2V1\Delta G_{T} = nRT\ln\frac{V_{2}}{V_{1}} ΔGT=nRTlogP1P2\Delta G_{T} = nRT\log\frac{P_{1}}{P_{2}}

ΔGT=nRTlogV2V1\Delta G_{T} = nRT\log\frac{V_{2}}{V_{1}}

Explanation

Solution

1atm1atm …..(i)

100oC100^{o}C ….(ii)

On multiplication of eq. (ii) by 2 and than adding in

eq. (i)

1atm1atm …(iii)

On subtracting eq. (iii) by following eq.

ΔG\Delta G we get,
