Question:

Match List I (Equations) with List II (Types of processes) and select the correct option:
List I List II
Equation Types of process
(a) Kp > Q (i) Non-Spontaneous
(b) ΔGo < RT ln Q (ii) Equilibrium
(c) Kp = Q (iii) Spontaneous and endothermic
(d) T > ΔH/ΔS (iv) Spontaneous

a-(i),b-(ii),c-(iii),d-(iv)

a-(iii),b-(iv),c-(ii),d-(i)

a-(iv),(b-(i),c-(ii),d-(iii)

a-(ii),b-(i),c-(iv),d-(iii)

Solution:

When Kp > Q, rate of forward reaction > rate of backward reaction. Therefore, Reaction is spontaneous.
When ΔGo < RT ln Q, ΔG < 0. Therefore, Reaction is spontaneous.
When Kp = Q, rate of forward reaction = rate of backward reaction. Therefore, Reaction is in equilibrium.
When T > ΔH/ΔS, ΔG = ΔH - TΔS < 0. Therefore, Reaction is spontaneous and endothermic.
