The rate of a reaction may be expressed as: + 1/2 d[C]/dt = - 1/3 d[D]/dt = + 1/4 d[A]/dt = - d[B]/d — Chemical Kinetics Chemistry Question

💡 Solution & Explanation

The negative sign indicates reactants (B and D) and the positive sign indicates products (A and C). The stoichiometric coefficients are the denominators. Rate = -d[B]/dt = -1/3 d[D]/dt = +1/4 d[A]/dt = +1/2 d[C]/dt. This implies 1 mole of B reacts with 3 moles of D to form 4 moles of A and 2 moles of C. Therefore, correct answer is B.
