Question

Higher yield of NO in \[\ce{N2(g) + O2 <=> 2NO(g)}\] can be obtained at:

[ΔH of the reaction = +180.7 kJ mol⁻¹]

1. higher temperature
2. lower temperature
3. higher concentration of N₂
4. higher concentration of O₂

Choose the correct answer from the options given below:

Options

• A, D only

• B, C only

• B, C, D only

• A, C, D only

Answer 1

A, C, D only

Explanation:

1. As the temperature increases, the reaction shifts forward.
2. As the temperature decreases, the reaction shifts backward.
3. As the concentration of N₂ increases, the reaction shifts forward.
4. As the concentration of O₂ increases, the reaction shifts forward.
