Question

The effect of temperature on spontaneity of reactions are represented as : H S Temperature Spontaneity (A) + – any T Non Spontaneous (B) + + low T Spontaneous (C) – – low T Non Spontaneous (D) – + any T Spontaneous The incorrect combinations are:

(A) (B) and (D) only
(B) (A) and (C) only
(C) (B) and (C) only
(D) (A) and (D) only

Prashant Kotian · Accepted Answer

Correct answer: C. H S Temperature Spontaneity (A) + – only T G = +ve, No ; non spontaneous (B) + + Low T G = –ve, Yes ; spontaneous (C) – – Low T G = –ve, Yes ; spontaneous (D) – + only T G = –ve, Yes ; spontaneous (B) & (C) are incorrect
