Question

Consider the general reaction given below at 400 K xA(g) yB(g) The values of Kp and Kc are studied under the same condition of temperature but variation in x and y. (i) Kp = 85.87 and Kc = 2.586 appropriate units (ii) Kp = 0.862 and Kc = 28.62 appropriate units The value of x and y in (i) and (ii) respectively are:

(A) (i) 3, 1 ; (ii) 3, 1
(B) (i) 4, 1 ; (ii) 4, 1
(C) (i) 1, 3 ; (ii) 2, 1
(D) (i) 1, 2 ; (ii) 2, 1

Correct answer: D. For reaction (i) : KP > KC ng > 0 y – x > 0. 85.87 = 2.586 (0.0821 × 400) y–x Solving y – x 1 For reaction (ii) : KP < KC y – x < 0. SECTION-B
