For a reaction, \(A \rightleftharpoons P,\) the plots of [A] and [P] with time at temperatures T1 and T2 are given below. (2018)
(Assume \(\Delta \mathrm{H}^{\mathrm{o}}\) and \(\Delta \mathrm{S}^{0}\) are independent of temperature and ratio of lnK at T1 to lnK at T2 is greater than T2/T1. Here H, S, G and K are enthalpy, entropy, Gibbs energy and equilibrium constant, respectively.)
(Assume \(\Delta \mathrm{H}^{\mathrm{o}}\) and \(\Delta \mathrm{S}^{0}\) are independent of temperature and ratio of lnK at T1 to lnK at T2 is greater than T2/T1. Here H, S, G and K are enthalpy, entropy, Gibbs energy and equilibrium constant, respectively.)
- \(\Delta \mathrm{H}^{\circ}<0, \Delta \mathrm{~S}^{\circ}<0\)
- \(\Delta \mathrm{G}^{\circ}<0, \Delta \mathrm{H}^{\circ}>0\)
- \(\Delta \mathrm{G}^{\circ}<0, \Delta \mathrm{~S}^{\circ}<0\)
- \(\Delta \mathrm{G}^{\circ}<0, \Delta \mathrm{~S}^{\circ}>0\)
Answer
(A) H ^ <0, ~S ^ <0, (C) G ^ <0, ~S ^ <0
