Mean rates of reaction.

Question 1

What does time to product formed graph look like?

Answer 1

• First:
• The reaction is vert fast as alot of the reactant is being used up in the reaction to form the product. There is a lot of reactant molecules.

Second:
- The reaction slows down as a lot of the reactant molecules have already reacted and formed the product. Fewer reactant molecules.

• Slope is flat:
• Reaction has stopped as all reactant molcules have been used uo.

Solid=g.
Gas= cm^3

Question 2

How do we calculate the mean rate of reaction?

Answer 2

• Mean Rate of Reaction= Quantity of Product formed/time.
  (g/s)(
  (cm^3/s)

Question 3

How do we use tangenets to find the rate of reaction?

Answer 3

• Draw an tangent on the point we are interested in.
• Construct a triangle.
• Find the lengths of the sides of the triangle. grams and time.
• Divide Height by width.
