Re: zero, first, and second order
The proportion of rate to concentration is the difference. In a first order reaction, the rate is proportional to the concentration. In a second order reaction, rate is proportional to the concentration raised to a power of two. Lastly, a third order reaction, the rate is proportional to a concentration raised to the third power. But, these conditions are true only if there is one reactant. If there are many, the powers of all the reactants must add up to the type of order the reaction is. For example, a third order reaction can have one reactant raised to the first power and the other reactant raised to the second power. The total of both exponents adds to three.

Re: zero, first, and second order
Thanks for the helpful answer. But I'm still unclear why it's important to know these things and what they can help us learn about chemistry?
