48. Solution to Chemistry Problem

2. A first-order sequential reaction proceeds according to the scheme
A k1→P k2→B The initial concentration of the starting substance is [A]0. Calculate:
1) the coefficients of the maximum of the curve [P]=f(t) (the maximum concentration of the intermediate product and the time it is achieved); 2) the time to achieve t1 the concentration of the starting substance [A]1; 3) the concentrations 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 [A] = f(t) and [P] = f(t); 7) based on the data obtained, plot the graph [P]=f(t).
