Question

Two reactants combine to form a product in the reaction A + BC. The rate of the

reaction depends on the concentrations of both reactants squared (rate = K[A]²[B]²).
What's the total reaction order of this reaction?
OA) 3
OB) 4
OC) 2
OD) 1

Answer 1

The total reaction order of a chemical reaction is determined by adding up the individual orders with respect to each reactant. In this case, the rate equation is rate = K[A]²[B]², which indicates that the reaction order with respect to reactant A is 2 and the reaction order with respect to reactant B is also 2.

To calculate the total reaction order, we add up the individual orders: 2 + 2 = 4.

Therefore, the total reaction order of the given reaction is 4. Option (OB) is the correct answer.
