A reaction occurs spontaneously is
Options
(a) TΔS < ΔH and both ΔH and ΔS are +ve
(b) TΔS > ΔH and ΔH is +ve and ΔS is -ve
(c) TΔS > ΔH and both ΔH and ΔS are +ve
(d) TΔS = ΔH and both ΔH and ΔS are +ve
Correct Answer:
TΔS > ΔH and both ΔH and ΔS are +ve
Explanation:
ΔG = ΔH – TΔS .
ΔG = -ve for spontaneous reaction , When ΔS = +ve, ΔH = +ve and TΔS > ΔH ⇒ ΔG = -ve, When randomness favours and energy factor do not favour then spontaneity depends upon the temperature dependent means at high temperature. TΔS > ΔH, ΔG = -ve and reaction is feasible.
