Under what pressure must an equimolar mixture of SO 2 and Cl 2 be placed at a given temperature to obtain 60% conversion of SO 2 into SO 2 Cl 2 ? Given: SO 2 (g) + Cl 2 (g) ⇌ SO 2 Cl 2 (g); K p = 1.5 atm -1

Take 1 mol each; 60% conversion gives SO₂Cl₂ = 0.6 and SO₂ = Cl₂ = 0.4 mol Total moles = 0.4 + 0.4 + 0.6 = 1.4

K_p = ((0.6/1.4)P)/([(0.4/1.4)P]²) = ((0.6)(1.4))/((0.4)²P) = 5.25/P

5.25/P = 1.5, so P = 3.5 atm

This is option (a).
