Chemistry 6.1.5

Question 1

What are the 4 Factors that Affect the Rate of Reaction? (4)

Answer 1

-Concentration / Pressure.

-Temperature.

-Surface Area.

-Catalyst.

Question 2

Why is it Economically Important to have a Higher ROR?

Answer 2

Because it means that the Reaction is more Efficient, hence is more Sustainable.

Question 3

Explain the Link between Concentration of a Solution & the ROR.

Answer 3

With Increased Concentration of a Solution, the Rate of Reaction will Increase. Concentration & ROR are Directly Proportional.

Question 4

Explain the Link between Temperature & ROR.

Answer 4

Temperature & ROR are Directly Proportional.

Question 5

Explain the Link between Surface Area of Solid Reactants & ROR.

Answer 5

The SA of Solid Reactants is Directly Proportional to the ROR.

Question 6

Explain the Link between Catalyst Usage & ROR.

Answer 6

With a Catalyst, the ROR will Increase. Because it Provides an Alternate Pathway, with a Lower Activation Energy.
