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

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.

bcde is the incorrect answer it is a
