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

If k = 7.66 x 10^-4 s^-1 and the initial concentration of A is 0.86 mol L^-1, what is the half life of this reaction in 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".
