Answer:
Reaction 2 is 2.333 times faster than reaction 1.
Explanation:
The reaction rate is measured considering the concentration of reactant used or product made and the time interval. This can be expressed in the following equation:
Therefore, the higher the concentration of reactant used, the faster the reaction will be. If we consider that both Reaction 1 and Reaction 2 happen during the same time interval (Δt), we can express their rates:
Dividing R2 per R1:
Thus, Reaction 2 is 2.333 times faster than Reaction 1.
