Rate equations

Question 1

Describe the three concentration time graphs graphs for different order reactants

Answer 1

0 order - straight
first and second order curved hard to distinguishWH

Question 2

What type of graph should be plotted to discern the order of a reactant

Answer 2

Rate- concentrationW

Question 3

What does the rate-concentration graph look like for a first order reactant

Answer 3

straight flat line

Question 4

What does the rate-concentration graph look like for a second order reactant

Answer 4

Directly proportional straight line increase

Question 5

What does the rate-concentration graph look like for a third order reactant

Answer 5

Exponential increase

Question 6

Which rate is used to plot rate graphs

Answer 6

Initial rate at t=0

Question 7

State the arrhenius equation

Answer 7

k= A e^-Ea/RT

Question 8

define every part of the arrhenius equation

Answer 8

k - constant
A - pre exponsnetial facotr
Ea activation energy
R gas constant
T temp in kelvin

Question 9

ln equation of arrhenuus

Answer 9

lnk= -Ea/RT +lnA

Question 10

ln arrhenius for EA

Answer 10

Ea = (lnA-lnK)RT

Question 11

What two values do you plot for an arrhenius plot

Answer 11

1/T x
lnK on y

Question 12

What values can you obtain from an arrhenius plot

Answer 12

lnA - from y intercept
gradient = -Ea/R
