Which of the following changes would cause a reaction to proceed slower? Choose two.
Increase in temperature
Decrease in temperature
Increase in reactant concentration
Decrease in reactant concentration
What is the rate law of the following reaction?
2A + B -> C + D
Rate = k 2[A][B]
Rate = k[C][D]
Rate=k [A]2[B][C][D]
Rate = k[A]2[B]
Given the information in the chart, what is the reaction order?
Zero
First
Second
Third
Given the rate law of Rate = [A]2[B], what would be the result if the concentrations of A and B were both doubled?
The rate will double
The rate will quadruple
The rate will increase by a factor of 8
The rate will remain the same.
[Requires Calculator] After 6 minutes, 92% of a substance remains. Knowing this is first-order, what is the half life of the substance (in minutes)?
38 minutes
48 minutes
54 minutes
50 minutes
What is the role of D in this reaction?
Catalyst
Intermediate
What effect does an increase in temperature have on the activation energy of a reaction?
Lowers the activation energy
Increases the activation energy
Increasing the temperature has no effect on the activation energy
What is the rate law of this reaction?
R = k[NO2]2
R = k[NO2][CO]
R = k[NO3][CO]
