Notes

Which of the following is most likely to increase the rate at which the reaction occurs?
Which one of the following is responsible for increasing the speed of a chemical reaction? Catalyst

A catalyst increases the rate of a chemical reaction by lowering the activation energy.
A catalyst can only help in reaching the equilibrium of a reaction MORE QUICKLY but cannot alter a reaction's equilibrium.

A catalyst: both b & c
The catalyst managanese (IV) oxide, MnO2 is used in the:

The use of a catalyst changes which of the following? Decomposition of hydrogen peroxide

Red is an atom of element X
Blue is an atom of element Y
Green is an atom of element Z
When an atoms of element Z (a catalyst) were introduced to a vessel?

The diagram above illustrates the effect of a catalyst for the reaction. energy change? 15 start pass 25 high 10 end

Which of the following is not affected by enzymes and chemical catalysts? Equilibrium constant

Which of the following explains the increase of the reaction rate by a catalyst? The catalyst provides an alternative path

For the following system at equilibrium? 16kcal + N2(g) The amount of products would not change with any catalyst

For the following system at equilibrium 16 kcal + N2(g) + 2O2(g) 2NO2(g)? It would increase the rate.

Where, in a chemical equation, is the formula of a catalyst shown? above the yield arrow.

What is the effect of catalyst when it is added to a system at equilibrium? Activated energy decreases.

Which of the following correctly illustrates the effect of a catalyst to a reaction?
2 line to 1 line top green light up in between

What effect does a catalyst have on the rate of a reaction? It Increases the rate

The rate of a reaction is increased with the addition of a catalyst. Which letter represents the activation energy of the catalyzed reaction? (A-E: B) (A-E: D) (A-E: C)

Which of the following correctly illustrates the effect of a catalyst if one was introduced to the diagram above?

Is the H for the process affected by a catalyst? No
By adding a catalyst the system will reach equilibrium faster. True

A catalyst for the decomposition of hydrogen peroxide is?

True or False: The above diagram correctly illustrates the effect of a catalyst on a reaction. True

For the graph above the red line could represent catalyst is added. True

A catalyst is a substance that enhances the speed of rate of a reaction without being consumed in the reaction. True

Catalysts never help in reducing the activation energy barrier. False
