Chemistry Question from JEE Main 2026 · 23 January, Shift 1

Consider the general reaction given below at 400K400 \, \text{K}: xA(g)yB(g)xA(\text{g}) \rightleftharpoons yB(\text{g}). The values of KpK_p and KcK_c are studied under the same condition of temperature but variation in xx and yy. (i) Kp=85.87K_p = 85.87 and Kc=2.586K_c = 2.586 (ii) Kp=0.862K_p = 0.862 and Kc=28.62K_c = 28.62. The values of xx and yy in (i) and (ii) respectively are :

  • A

    4,14,1 4,14,1

  • B

    3,13,1 3,13,1

  • C
