How do you determine a rate?

experimentally or from stoichometry

only experimentally. rate cannot be determined using stoichiometry. 

200

finding concentration for t when concentration of A falls 1/10 of the initial 

0.1=e^-kt

ln0.1=-kt

ln0.1/k=t

500

State the Arrhenius Equation. 

K=Ae^-Ea/RT

What is Half life?

time needed for half of the rxn to be consumed. 

500

second order rate law reaction equations.

1/[A]-1/[A]₀=2kt

Kinetics

100

Is activation energy always negative or positive?

activation energy is always positive because the slope is always negative because the rate usually decreases over time!
