rate of reaction

Question 1

rate equation

Answer 1

rate= k[A][B]
= K x [A]^m[B]^n
m+n = overall order for reaction
rate units= mol-1dm^3s^-1
k= rate constant

Question 2

rate constant features

Answer 2

K
temperature dependent
different units for different reactions
- units of rate = conc/time
THE LARGER THE RATE CONSTANT THE FASTER THE REACTION

Question 3

rate definition

Answer 3

change in concentration of a reactant or product over time
rate= gradient of a conc/time graph

Question 4

RDS

Answer 4

slowest step in a reaction
- because it has the highest activation energy for a successful collision

Question 5

RDS and reaction mechanism

Answer 5

reactants in the rate equation are involved in the rate determining step
- mechanism must involve them colliding at some point
