SATHEE: Thermodynamics Question 81

Thermodynamics Question 81

Question: For which one of the following reactions, $Δ H$ is not equal to $Δ E$

[IIT JEE 1995]

Options:

A) $H_{2 (g)} + I_{2 (g)}$ ⇌ $2 H I_{(g)}$

B) $C_{(s)} + O_{2 (g)}$ ⇌ $C O_{2 (g)}$

C) $N_{2 (g)} + 3 H_{2 (g)}$ ⇌ $2 N H_{3 (g)}$

D) $H C l_{(a q)} + N a O H_{(a q)}$ ⇌ $N a C l_{(a q)} + H_{2} O$

Show Answer

Answer:

Correct Answer: C

Solution:

In this reaction $Δ n = 2 - 4 = - 2$ so $Δ H \neq Δ E$ .
