Kinetics,Equilibria and Redox Reactions and collision theory

Question 1

What are a range of factors affecting the rate of chemical reactions?

Answer 1

1)Surface Area
2)Temperature
3)concentration and pressure

Question 2

How do you calculate the rate of reaction?

Answer 2

rate of reaction=amount of reactants or product/time

Question 3

What are some of the other ways to measure the rate of reaction?

Answer 3

1)Use a colorimeter to measure the appearance of a colored product or disappearance of a colored reactant.

2)Measure the loss of mass in a reactant that produces a gas.

3)Measure the time taken for enough precipitate to form so that a cross drawn under the flask is no longer visible.

4)The iodine clock reaction

Question 4

What is activation energy?

Answer 4

the minimum amount of energy required to start a reaction.

Question 5

What is an Exothermic reaction?

Answer 5

reactions that give out heat.

Question 6

What is an endothermic reaction?

Answer 6

Reactions that take in heat.

Question 7

What are some of the advantages of using a catalyst in industrial reactions?

Answer 7

-Using catalysts leads to faster, more energy-efficient chemical reactions.

-Catalysts are used to increase the rate of reactions so minimizing the size and cost of a plant.

Question 8

What is the Maxwell Boltzmann distribution?

Answer 8

A maxwell boltzmann distribution of molecular energies is a plot of the number of gas molecules against their energy.
