CFCs are used in the manufacturing of some types of plastics and foams. Think of something you use every day that is made of plastic or foam, and imagine if it were made of an alternate substance. How would it be the same? How would it be different?

The first-order reaction a→2b+c has rate constant 0.538 s−1. if the initial concentration of a is 0.867 mol l−1, what is the half-life of the reaction in seconds? remember to use correct significant figures in your answer (round your answer to the nearest hundredth). do not include units in your response.
