New cards

what is the symbol for the rate constant

k

2
New cards

how can k be calculated

using the initial rate and the rate equation

3
New cards

if the rate equation is rate = k[A][B] how do we calculate k?

rearrange

k = rate/[A][B]

4
New cards

what are the units for the rate constant of a zero order

mol dm-3 s-1

5
New cards

what are the units for the rate constant of a first order

s-1

6
New cards

what are the units for the rate constant of a second order

mol-1 dm3 s-1

7
New cards

what are the units for the rate constant of a third order

mol-2 dm6 s-1

8
New cards

what are the units for the rate constant of a fourth order

mol-3 dm9 s-3

9
New cards

what happens to the ROR as the rate constant increases

the rate of reaction increases

10
New cards

what happens to the rate constant and so the ROR when temp increases

rate constant and ROR increases

11
New cards

how can we describe the relationship between the rate constant and temperature

exponential
