Question

The standard entropies of N, (g), H, (g) and
NH, (g) are 191.5, 130.5, 192.6 JK-1 mol-1. The
value of AS° of formation of ammonia is
(1) -98.9 JK-1 mol-1 (2) Zero
(3) +129.4 JK-1 mol-1 (4) -29.4 JK-1 mol-1
Correct ans- 1​

Answer 1

Answer:

correct option is 1 of this question

Answer 2

Answer:

(1) -98.9 J K⁻¹ mol⁻¹

Explanation:

Entropy of formation = Standard entropy of Product - Standard entropy of reactants.

The only thing to keep in mind is to balance the equation so that we have only 1 mole of the product.
