Question

Predict the conditions for forward reaction on the basis of Le-Chatelier's principle.

\[\ce{2SO2(g) + O2(g) ⇌ 2SO3(g)}\]; ΔH = −198 kJ

विकल्प

• Lowering the temperature and increasing pressure.

• Any value of temperature and pressure.

• Lowering of temperature as well as pressure.

• Increasing temperature as well as pressure.

Answer 1

Lowering the temperature and increasing pressure.

Explanation:

An increase in pressure favours a reaction that shows a drop in mole or volume while an increase in temperature favours endothermic reactions.
