What can be said about the stoichiometric coefficients of a balanced chemical reaction AND the powers to which the concentrations are raised in the rate-law expression?
There is an exact relationship between the two
Not much can be said except that this no relationship
The powers can be equal to the number of molecules that are formed
The powers are euqal to the number of molecules that must collide and react in the fastest step
The powers equal the coefficients of the equation for the reaction at 298 K
