Concept explainers
Experiments show that if the chemical reaction
takes place at 45°C, the rate of reaction of dinitrogen pent-oxide is proportional to its concentration as follows:
(See Example 3.7.4.)
(a) Find an expression for the concentration [N2O5] after t seconds if the initial concentration is C.
(b) How long will the reaction take to reduce the concentration of N2O5, to 90% of its original value?

- Suppose that the initial mass of radioactive substance is m0 and the half-life of the substance is h. Let m(t) be the mass remaining at time t. a What is meant by the half-life h? b Write a formula for m(t) in terms of the half-life h. c Write a formula for the relative decay rate r in terms of the half-life h. d Write a formula for m(t) in terms of the relative decay rate r.arrow_forwardThe formula for an increasing population is given by p(t)=P0ert where P0 is the initial population and r0. Derive a general formula for the time t it takes for the population to increase by a factor of M .arrow_forward
