    1.) Compare two chemical reactions, one requiring simultaneous collision of three molecules and the other requiring a collision between two molecules. Assuming all else is equal, which reaction should be faster? Explain your answer. Can you provide an example?

    2.) Why do foods cook faster in a pressure cooker relative to an open pot of boiling water?

    1.) Compare two chemical reactions, one requiring simultaneous collision of three molecules and the other requiring a collision between two molecules. Assuming all else is equal, which reaction should be faster? Explain your answer. Can you provide an example?

    Here's an example of a termolecular reaction, a reaction involving the simultaneous collision of three molecules, ions, or atoms. This is the oxidation of nitric oxide to form nitrogen dioxide.
    2 NO + O2 -------> 2 NO2

    Here's an example of a bimolecular reaction. It is the oxidation of sulfur to form sulfur ...

    Solution Summary

    370 words give an example to illustrate whether reactions requiring less molecular collisions are faster, as well as how a pressure cooker speeds cooking times.
