Question

1.) The reaction A(aq) ---> B(aq) is a first order reaction with respect to A(aq). The concentration of A(aq) is reduced to 26.2 % of its initial value in 1.61 minutes. What is this reaction's half-life (in s)?

2.) The reaction A(aq) ---> B(aq) + C(aq) is a first order reaction. The half-life of A(aq) is 94.8 s at 25.0oC and its half-life is 65.6 s at 45.0oC. What is its half-life (in s) at 65.0oC?

3.) The half-life of 14C is 5730 years. A sample contains 90.8 % of the 14C that it would contain if it were still part of a living being. What is the age (in years) of this sample?
