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 33.1 % of its initial value in 1.54 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 91.0 s at 25.0oC and its half-life is 69.2 s at 45.0oC. What is its half-life (in s) at 65.0oC? ...

1. The half-life of carbon-14 is 5730 years. A sample is found to have one-eighth the original amount of carbon-14 in it. How old is the sample? 5730 years, 716 years, 45800 years, 17200 years 2. Why wouldn't you use carbon-14 dating on a piece of shell that was estimated to be 1 million years old? Sea shells do not have radioisotopes, carbon dating is only useful on plants, uranium dating is better for items older than 1/2 million years,...

Question 2 : The reaction A(aq) ---> B(aq) + C(aq) is a first order reaction. The half-life of A(aq) is 87.1 s at 25.0°C and its half-life is 65.8 s at 45.0°C. What is its half-life (in s) at 65.0°C? Question 3 : The half-life of 14C is 5730 years. A sample contains 90.9 % 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?
