kinetics

Question 1

how to tell from the rate equation if a reaction has more than one step

Answer 1

numbers of chemicals in the reaction equation don’t match the rate equation

Question 2

how is initial rate of reaction calculated from a concentration-time graph

Answer 2

find gradient of the tangent at t = 0

Question 3

why would a reaction have order zero for one of its reactants

Answer 3

reactant is not involved in rate determining step (also means there is more than one step)
