what is the symbol for the rate constant
k
how can k be calculated
using the initial rate and the rate equation
if the rate equation is rate = k[A][B] how do we calculate k?
rearrange
k = rate/[A][B]
what are the units for the rate constant of a zero order
mol dm-3 s-1
what are the units for the rate constant of a first order
s-1
what are the units for the rate constant of a second order
mol-1 dm3 s-1
what are the units for the rate constant of a third order
mol-2 dm6 s-1
what are the units for the rate constant of a fourth order
mol-3 dm9 s-3
what happens to the ROR as the rate constant increases
the rate of reaction increases
what happens to the rate constant and so the ROR when temp increases
rate constant and ROR increases
how can we describe the relationship between the rate constant and temperature
exponential
