Equations Topic 6/16

Question 1

Rate Equations

Answer 1

0th order: R = k
1st order: R = k [A]
2nd order: R = k [A][B]
for the reaction A + B -> products

where
[] = concentration of
k = rate constant

Question 2

Arrhenius equation

Answer 2

k = Ae^(-Ea / RT)

where
k = rate constant
Ae = Arrhenius constant
Ea = activation energy
R = gas constant
T = temperature

Question 3

Two experiments at different temperatures

Answer 3

ln (k1 / k2) = Ea / R * (1 / T2 - 1 / T1)

where
k = rate constant
Ea = activation energy
R = gas constant
T = temperature
