Reaction Rate Investigation-

Introduction-

Background Information-

The reaction rate is the rate of which the reactant reacts with the reactor.

We will measure the rate of reaction by measuring the volume of gas let off by the reaction.

In order to find the average rate I will use the equation below.

Aim-

The aim of this investigation is to find how the surface area effects the reaction rate in the reaction between calcium chloride and hydrochloric acid.

Hypothesis-

I think that with a greater surface area(smaller particles) the acid will react quicker.

I think this because of the collision theory. In the collision theory it states that in order for two substances to react together they must collide with each other and they must have enough energy.

Procedure-

Variables-

Independent

Dependent

Control

The concentration of the acid

Rate of reaction (volume of gas)

Volume of HCL (1 mol l-1)

Temp. (room temp)

Mass of Calcium Carbonate(2.5g)

Volume of Dilute HCL (50 cm3)

Time (40 seconds)

Agitation (none)
