64. Solving a chemistry problem

1. The reaction is described by the equation 2A B → 2C. The initial concentrations of substances A and B are 0.3 and 0.5 mol/l, respectively. The reaction rate constant is 0.8 l2•mol–2•min–1. Calculate the initial rate of the reaction and its rate after some time, when the concentration of substance A decreases by 0.1 mol•/l.
