46. Solving a chemistry problem

A sequential first-order reaction proceeds according to the scheme A k1→P k2→B

The initial concentration of the starting substance is [A]0. Calculate:
1) curve maximum coefficients [Р]=f(τ) (maximum concentration of intermediate product and time to reach it); 2) the time τ1 to reach the concentration of the initial substance [A]1 3) the concentration of P and B at time τ 1; 4) the time during which the concentration of the intermediate product becomes equal to [Р]1 5) the coordinates of the inflection point of the curve [В] = f(τ); 6) the point of intersection of the curves [А] = f(τ) and [Р] = f(τ); 7) build graphs of dependences of concentration A, P and B on time.
