Match Column I with Column II
Column I | Column II |
|---|---|
P) 2SO3(g) ⇌ 2SO2(g) + O2(g) | i) Extent of reaction will not increase with increase in pressure |
Q) N2(g) + O2(g) ⇌ 2NO(g) | ii) Concentration of product will increase with increase in temperature |
R) 2NO2(g) ⇌ N2O4(g) | iii) Increase in volume will increase moles of reactant |
| iv) Introduction of inert gas at constant pressure will shift the equilibrium in the product side |
Options:
Answer:
Solution:
P: Δ ng = +1, so a pressure rise cannot increase the extent (i); decomposition of SO3 is endothermic, so product concentration rises with temperature (ii); inert gas at constant pressure shifts toward more moles, the product side (iv) Q: Δ ng = 0, so pressure cannot increase the extent (i); formation of NO is endothermic (ii)
R: Δ ng = -1; increasing the volume shifts the equilibrium backward, so moles of reactant increase (iii); the reaction is exothermic and pressure increases the extent, so (i), (ii), (iv) do not apply
The correct mapping is option (c).
