These are fun, qualitative puzzles to test your understanding of reaction rates. See what you come up with individually and then arrive at a group consensus. Write a paragraph or two stating and supporting your conclusion.
You will love stoichiometric tables after constructing them for these four reactions :-) For the gas phase reactions, express the concentration in terms of partial pressure too.
Here is a stoichiometry problem for all of you bio-types.
