Two isomers (a and b) of a given compound dimerize as follows.2a (sub)> a(sub)(sub)> b(sub)2both processes are known to be second order in reactant, and k1 is known to be 0.207 l/mol·s at 25°c. in a particular experiment a and b were placed in separate containers at 25°c, where [a]0 = 1.00 x 10 -2 m and [b]0 = 2.50 x 10 -2 m. it was found that after each reaction had progressed for 3.25 min, [a] = 3.00[b]. in this case the rate laws are defined as the following. rate = )[a])/(delta)t = k(sub)1[a]^2rate = )[b])/(delta)t = k(sub)2[b]^2(a) calculate the concentration of a2 after 3.25 min.(b) calculate the value of k2.(c) calculate the half-life for the experiment involving a.
