The incorrect statement among the following, for this reaction, is:
Decrease in the total pressure will result in formation of more moles of gaseous X
At the start of the reaction, dissociation of gaseous X2 takes place spontaneously
βequilibrium = 0.7
Kc < 1

(A) Correct statement. As on decrease in pressure reaction move in direction where no. of gaseous molecules increase
(B) Correct statement
At the start of reaction QP < KP so dissociation of X2 take place spontaneously
(C) Incorrect statement as KP = 8βeq2 / 4 - βeq2 = 8 × (0.7)2 / 4 - (0.7)2 > 1
(D) Correct statement. As ΔG0 > 0 ΔG0 = -RTlnKP ΔG0 > 1, So KP should be less than 1. So K < 1
KP = KC(RT)Δng (RT > 1)
KC = KPRTKc < KP So, KC < 1
