Physical Chemistry Question on Thermodynamics
Identify the reaction for which, at equilibrium, a change in the volume of the closed reaction vessel at a constant temperature will not affect the extent of the reaction
A
CaCO3 (𝑠) ⇌ CaO(𝑠) + CO2(𝑔)
B
H2 (𝑔) + I2 (𝑔) ⇌ 2HI(𝑔)
C
2NO2 (𝑔) ⇌ N2O4 (𝑔)
D
CO2 (𝑠) ⇌ CO2 (𝑔)
Answer
H2 (𝑔) + I2 (𝑔) ⇌ 2HI(𝑔)
Explanation
Solution
The correct option is (B): H2 (𝑔) + I2 (𝑔) ⇌ 2HI(𝑔)
