Consider the following reaction: ch3br(aq)+oh−(aq)→ch3oh(aq)+br−(aq) the rate law for this reaction is first order in ch3br and first order in oh−. when [ch3br] is 5.0×10−3m and [oh−] is 0.050 m, the reaction rate at 298 k is 0.0432 m/s.

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.

catya that's not even a b or c
