Two problems... i need help on these ASAP.

6. A solution containing 10mmol/L A reacts to form B and C. The reaction proceeds with the following kinetics: ABC If k1=0.025/min and k2=0.10/min and there is no B or C in the solution at the beginning of the reaction: a. What order is each reaction? b. At what time is B at its maximum? c. What is B's concentration at this time? 7. You are studying the following parallel (competing) reactions in lab: A+ABA+AC Reaction 1 Reaction 2 You begin with an initial concentration of 5mmol/L of A and previous measured k1= 0.025L/mmolmin. At 10 minutes, you measure A and note that the concentration of A= 1.2mmol/L. a. If you assume reaction 2 is also second order, what is k2 ? b. Qualitatively (in words, without calculations), how would the concentration of A at 10 minutes change (in comparison to the 1.2mmol/L you measured) if k2 increased to 1.5 L/mmol*min
