6) Unit 1 - Reaction Feasibility AND KINETICS

Question 1

what formula would be used to find at what temperature something becomes feasible

*what must you remember when using this formula

Answer 1

T=AH/AS

remember to convert either ΔH or ΔS,

*can make ΔS into kj by dividing by 1000

Question 2

The MORE ordered a system the ______ entropy it has

The LESS ordered a system the ______ entropy it has

Answer 2

The more ordered a system the less entropy it has

the less ordered a system the more entropy it has

Question 3

how can you convert degree to kelvin

Answer 3

+273

Question 4

what is the rate equation

Answer 4

Rate = k[A]^x[B]^y

where x and y are the order of reaction

Question 5

if a when a concentration is double and the rate has no change then the order for that reaction is

Answer 5

0

Question 6

if a when a concentration is double and the rate doubles then the order for that reaction is

Answer 6

1

Question 7

if a when a concentration is double and the rate quadruples, then the order for that reaction is

Answer 7

2

Question 8

rearrange the rate equation to be able to work out k

Answer 8

k = rate/[A]^x[B]^y

Question 9

if the overall order of a reaction is 0,1,2,3, what is the corresponding units for k

Answer 9

0 = mol l-1 s-1
1 = s-1
2= mol-1 l s-1
3= mol-1 l2 s-2

*all numbers are to the power
