Rates

Question 1

Rate equation

mA + nB → pC + qD

Answer 1

Rate = k [A]^m [B]^2n

Question 2

Arrhenius equation

Answer 2

K = A e^(Ea/RT)

(Ea must be in Jmol-1 so x10^3)

Question 3

Arrhenius equation to calculate Ea

Answer 3

ln K = ln A - Ea/RT

Question 4

Arrhenius equation on a graph - modelled as linear

Answer 4

ln K = -Ea/R . 1/T + ln A
y = m x + c
