At a constant temperature T, substance A begins to transform into the products 1, 2, and 3, according to the following parallel reaction mechanism: Ak1=3.4104s11Ak2=5103s12Ak3=2104s13 When the entire amount of A was consumed, the concentration of product P2 was measured to be 4.0101moldm3. Calculate the concentrations of the other products 1 and 3 as well as the initial concentration of substance A
