1
Q
units for rate constant: first-order reaction
A
s-1
2
Q
units for rate constant: second-order reaction
A
x^3 mol−1s−1
x = depends on context can be dm
3
Q
define: rate of reaction
A
the change in concentration of a particular reactant/product per unit time.
4
Q
arr eqn - when you know T1, T2 and K1, K2
A
lnK x (k1/k2) = Ea/R x (1/T2 - 1/T1)
5

A
increase in product conc/ change in time
or decrease in reactant conc/change in time
6
