In an experiment conducted last Tuesday, the time it takes for a certain reaction to proceed seems to be related to the initial concentration of one of the reactants A. Here is the data: Time Concentration of A 20 seconds 5 x 10^-2 M 5 seconds 10 x 10^-2 M With respect to the rate of reaction equation which depends upon the initial concentrations, what would the exponent of [A] be?
a. 0
b. 1
c. 2
d. 3
e. 4
