Question

*A reaction A + B → C +D + q has positive entropy change. The reaction is feasible at:*

1️⃣ High temp only
2️⃣ Low temp only
3️⃣ Any temp
4️⃣ Not feasible​

Answer 1

Answer:

1 high temperature only

Answer 2

In this reaction we see q ( heat) is being released so Delta H is negative.

Given is that delta S is positive, so according to formula-
/\G = /\H - T/\S

For reaction to be feasible, /\ G must be negative.

For /\G to be negative, temperature much be low

Answer is 2 - Low temp
