Determining Reactions

Postby Frenz Cabison 1B » Sun Mar 04, 2018 9:11 pm

How do we determine if something is zero-, first-, or second- order reaction?

One way we have learned to determine the order of each reactant in a reaction is the method of initial rates. Using this method we run many experiments and determine the order of each reactant by seeing how a change in initial concentration of a reactant changes the initial rate of the reaction. Adding the order of each reactant gives us the overall order of the reaction.

We can also use the k constant to narrow it down to what order it might be. 0 and 1storder have negative k constant and 2nd order has positive k constant.
