The Reaction, a + 2B Products, Was Studied

The reaction, A + 2B products, was studied. A timer was started when reagents A and B were mixed, and stopped when a specific quantity of product C accumulated. The data contains initial amounts of reactants used and the time needed to reach the specific quantity of C. Based on the data below, we can conclude that Hint: Remember reaction rate is proportional to 1/time.

A) the reaction is first order with respect to substance A.
B) the reaction is zero order with respect to substance A.
C) the reaction is one-half order with respect to substance A.
D) the reaction is second order with respect to substance A.
E) the reaction is third order with respect to substance B
