135. Solving a chemistry problem

AT 12. A sequential first-order reaction proceeds according to the scheme
A→k_1 P→k_2 B.
The initial concentration of the starting substance is [A]0. Calculate:
1) curve maximum coefficients [Р]=f(t) (maximum concentration of intermediate product and time to reach it); 2) the time t1 to reach the concentration of the initial substance [A]1 3) the concentration of P and B at time t 1; 4) the time during which the concentration of the intermediate product becomes equal to [P]1 5) the coordinates of the inflection point of the curve [B] = f(t); 6) the point of intersection of the curves [А] = f(t) and [Р] = f(t); 7) based on the data obtained, build a graph [P]=f(t).
