18.1 orders, rate equations and rate constants

Question 1

what is the rate of reaction proportional to?

Answer 1

the concentration of a particular reactant raised to a power

Question 2

what is zero order?

Answer 2

when the concentration of a reactant has no effect on the rate

Question 3

what is first order?

Answer 3

when the rate depends on its concentration raised to the power of one

Question 4

what is second order?

Answer 4

when the rate depends on its concentration raised to the power of two

Question 5

what is the rate equation?

Answer 5

rate = k [A][B]

Question 6

how do you work out the overall order of a reaction?

Answer 6

overall order= sum of orders with respect to each reactant
