For the reversible reaction, N2(g) + 3H2(g) ⇋ 2NH3(g) at 5000C, the value of Kp is 1.44 × 10-5 when partial pressure is measured in atmospheres. The corresponding value of Kc, with concentration in mole litre-1, is –
(a) 1.44 × 10-5/(0.082 × 500)-2
(b) 1.44 × 10-5/(8.314 × 773)-2
(c) 1.44 × 10-5 / (0.082 × 773)2
(d) 1.44 × 10-5 / (0.082 × 773)-2
