The rate constant for the reaction of A2 → 2A is 5.72 x 10-4 M-1min-1 at 25.0°C. If the initial concentration of A2 is 2

[answerhappygod]

The rate constant for the reaction of A2 → 2A is 5.72 x 10-4 M-1min-1 at 25.0°C.
If the initial concentration of A2 is 2.45 M, what will be its concentration after 35.0 days.
How long in hours, will it take for 85% of A2 to decompose?
A student recorded the half life of A2 as 1211.5 min. Explain why this answer is wrong.
