This is a two part question, please show work and I will rate you ! A)The rate constant for a certain reaction is k= 8.10×10?3 . If the initial reactant concentration was 0.150 M , what will the concentration be after 3.00 minutes? B)A zero-order reaction has a constant rate of 3.40×10^?4 M/s . If after 80.0 seconds the concentration has dropped to 3.00×10^?2 M , what was the initial concentration?
