Question

Match Column I with Column II

Column I	Column II
$P) 2NH_{3} (g) ⇌ N_{2} (g) + 3H_{2} (g)$	$i) Extent of reaction will not increase with increase in pressure$
$Q) 2HI(g) ⇌ H_{2} (g) + I_{2} (g)$	$ii) Concentration of product will increase with increase in temperature$
$R) 2(CH_{3} COOH)(g) ⇌ (CH_{3} COOH)_{2} (g)$	$iii) Increase in volume will increase moles of reactant$
	$iv) Introduction of inert gas at constant pressure will shift the equilibrium in the product side$

TestHub · Accepted Answer

P: Δ n g ​ = +2, so a pressure rise cannot increase the extent (i); dissociation of NH 3 ​ is endothermic, so product concentration rises with temperature (ii); inert gas at constant pressure shifts toward more moles, the product side (iv) Q: Δ n g ​ = 0, so pressure cannot increase the extent (i); dissociation of HI is endothermic (ii) R: Δ n g ​ = -1; increasing volume shifts the equilibrium backward, so moles of reactant increase (iii); dimerisation is exothermic and pressure increases the extent, so (i), (ii), (iv) do not apply The correct mapping is option (c). ​
