The rate of formation of HBr, +d[HBr]/dt is — Chemical Kinetics Chemistry Question
Question
The rate of formation of HBr, +d[HBr]/dt is
Answer: A
💡 Solution & Explanation
Rate = d[HBr]/dt = K2[Br][H2] + K3[H][Br2] - K4[H][HBr]. Substituting [H] and [Br] into this expression and simplifying leads directly to the standard HBr rate law: 2K2(K1/K5)^1/2[H2][Br2]^3/2 / (K3[Br2] + K4[HBr]). Therefore, correct answer is A.
