Acertain reaction has this form:   aa    bb. at a particular temperature and [a]0  = 2.00 x 10-2  molar, concentration versus time data were collected for this reaction and a plot of ln[a]t  versus time resulted in a straight line with a slope value of -2.97 x 10-2  min-1.how much time is required for the concentration of a to decrease to 2.50 x 10-3  molar? a.  70.03 minutesb.  0.0096 minutesc.  0.589 minutesd.  29.70 minutese.  100 minutes
