4. The dissociation of a dimer (A2) into two monomers (2 A) is given by the mechanism: k A₂ → 2A (k = 0.100 s¹ at 298 K). a. Write an expression of the rate law for this elementary reaction and integrate the rate law to generate an expression for the concentration of A2 as a function of time ([A₂](t)). b. Write an expression to calculate the concentration of A as a function of time ([A](t)). c. Calculate the concentration of monomer formed ([A](t)) and dimer remaining ([A₂](t)) after 10.0 seconds at 298 K, if [A₂]0= 1.00 M_and [A]o = 0. d. How long will it take (in seconds) to form 1.00 M monomer (A) using the same initial conditions above in part "c" ([A₂]0= 1.0 M and [A]o = 0)?
