Question 1

kinetics

Answer 1

shows how a chemical process occurs

Question 2

the rate law

Answer 2

aA+bB–> cC+dD. shows the relationship between the reaction rate and the concentrations of reactants

Question 3

k

Answer 3

rate constant. unique for each reaction

Question 4

orders of reaction

Answer 4

with respect to A and B have to be found experimentally

Question 5

increasing the concentration

Answer 5

increases the reaction rate. order of the reaction depends on this

Question 6

overall rate of a reaction

Answer 6

the sum of the powers of each individual reactant’s concentrations. so overall rate would be x + y

Question 7

zero order

Answer 7

no impact

Question 8

first order

Answer 8

doubles rate. ls -1

Question 9

second order

Answer 9

quadruples rate 2 mol-1 ls-1

Question 10

units for k

Answer 10

depend on the overall rate of reaction 3 mol-2 l2s-1

Question 11

determining step

Answer 11

the slow step of a reaction. the integers in the rate equation refer to the actual number of particles involved in the smaller step of the reaction
