1.	Spontaneity of a process is decided by the value of ΔG . A negative value of ΔG shows a spontaneous process. Since, the value of ΔG depends upon ΔG and ΔH, these two also play an important role for deciding spontaneity of a process. The condition for spontaneity of any chemical reaction, if (a) TΔS = ΔH and both ΔH and ΔS are positive (b) TΔS > ΔH and both ΔH and ΔS are positive (c) TΔS < ΔH and both ΔH and ΔS are positive (d) TΔS > ΔH and ΔH is positive and ΔS is negative
Answer» Correct Option (b) TΔS > ΔH and both ΔH and ΔS are positive Explanation : If ΔS = positive, ΔH = positive Then, ΔG will be negative if and only if TΔS > ΔH
