3.1.9 rate equations

Question 1

write a general equation for the rate

Answer 1

rate = k [A] ^m [B] ^n

Question 2

what is zero order?

Answer 2

concentration of a zero order reactant has no effect on rate of reaction
if you doubled the concentration, initial rate would be the same

Question 3

what is first order?

Answer 3

concentration of a first order reactant has a directly proportional relationship with rate
if you double concentration rate also doubles

Question 4

what is second order?

Answer 4

the concentration of a second order reactant has an even greater effect on rate of reaction
increasing concentration by a factor of y increases rate by y^2

Question 5

what is an order?

Answer 5

orders are the power of the concentration in the rate equation

Question 6

how do you calculate overall order?

Answer 6

add the orders together

Question 7

what is the rate determining step?

Answer 7

the slowest step

Question 8

what is the Arrhenius equation?

Answer 8

k = Ae -Ea/RT
k- rate constant
A - Arrhenius constant
e - exponential
Ea - activation energy
R - gas constant
T - temperature
