1)The following chemical reaction: A products shows first order kinetics with respect to A; rate = k[A].

Assume k = 1.59 x 10^-4 s^-1 .

If the initial concentration of A is 0.94 mol L^-1, what is the concentration of A (in mol L^-1) after 85.8 minutes?

Remember: if you want to express an answer in scientific notation, use the letter "E". For example "4.32 x 10⁴" should be entered as "4.32E4".

2)

The following chemical reaction: A products shows second order kinetics with respect to A; rate = k[A]².

If k = 13.09 x 10^-5 mol^-1 L s^-1 and the initial concentration of A is 0.61 mol L^-1, what is the half life of this reaction in hours?

Remember: if you want to express an answer in scientific notation, use the letter "E". For example "4.32 x 10⁴" should be entered as "4.32E4".
