Here we compare the first order and second order reaction based on Integrative rate laws. Reaction 1: A first order reaction (A > products) has the rate constant k = 0.483 min-1 (Rate = k[A]), and the initial concentration of reactant A is 0.800 M. Reaction 2: A second order reaction (B → products) has the rate constant k = 0.483 M-1 min-1 (Rate = k[B]?), and the initial concentration of reactant B is 0.800 M. Which of the following statements is true about these two reactions? Reaction 1 will take less time to change the reactant concentration from 0.800 M to 0.400 M than Reaction 2 will. Reaction 2 will take less time to change the reactant concentration from 0.800 M to 0.400 M than Reaction 1 b. will. Reaction 1 and Reaction 2 will take the same amount of time to change the reactant concentration from 0.800 M to 0.400 M. d. None of the above

Here we compare the first order and second order reaction based on Integrative rate laws.
Reaction 1: A first order reaction (A > products) has the rate constant k = 0.483 min-1 (Rate = k[A]), and the initial
concentration of reactant A is 0.800 M.
Reaction 2: A second order reaction (B > products) has the rate constant k = 0.483 M-1 min-1 (Rate = k[B]?), and
the initial concentration of reactant B is 0.800 M.
Which of the following statements is true about these two reactions?
Reaction 1 will take less time to change the reactant concentration from 0.800 M to 0.400 M than Reaction 2
will.
Reaction 2 will take less time to change the reactant concentration from 0.800 M to 0.400 M than Reaction 1
b.
will.
Reaction 1 and Reaction 2 will take the same amount of time to change the reactant concentration from 0.800
M to 0.400 M.
d. None of the above
