(Answered) Question 1 the reaction aaq ---gt baq is a first order

Academics

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 33.6 % of its initial value in 1.74 minutes. What is this reaction's half-life (in s)?

Question 2: The reaction A(aq) ---> B(aq) + C(aq) is a first order reaction. The half-life of A(aq) is 94.4 s at 25.0^oC and its half-life is 73.4 s at 45.0^oC. What is its half-life (in s) at 65.0^oC?

Question 3: The half-life of ¹⁴C is 5730 years. A sample contains 92.4 % 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
