If a reaction has two reactants, and doubling the concentration of one of them doubles the reaction rate, while doubling the concentration of the other leaves the reaction rate unchanged, what is the order of the reaction?

A) 0
B) ½
C) 2
D) 1 with respect to the first reactant, and 0 with respect to the second

Question

Madison Scifo · Accepted Answer

Final Answer : D, Explanation :  The reaction is first order with respect to the first reactant because doubling its concentration doubles the reaction rate, indicating a direct proportionality. It is zero order with respect to the second reactant because changing its concentration does not affect the reaction rate.
