For reaction: 4A + B -> 2C + 2D, the only incorrect statement is — Chemical Kinetics Chemistry Question

💡 Solution & Explanation

Rate of reaction = -1/4 d[A]/dt = -d[B]/dt = +1/2 d[C]/dt = +1/2 d[D]/dt. From this, d[C]/dt = 2 * (-d[B]/dt), which means the rate of appearance of C is twice (not half) the rate of disappearance of B. Hence, statement (b) is incorrect.
