Year 10 Rates of reaction quick check

1

The best explanation is:
Increasing concentration of a solution increases the rate of reaction as there are:

1

Increasing pressure of a gas increases the rate of reaction as there are:

1

Increasing surface area to volume ratio of a solid increases the rate of reaction as there are:

1

The rate of reaction for a powder is greater than the rate of reaction for small chips as there are:

1

As a reaction proceeds, the rate of reaction decreases and the slope of the tangent:

1

When one of the reactants is used up, the slope of the line (on a graph of concentration vs time):

5

Step 1: draw a _______ at t = 3s
Step 2: calculate the _______  of the tangent using change in _______ (g) / change in _______ 
(s)
Rate = _______ g/s


(note the values are in mass not in moles so the axis is incorrectly labelled!
What is the rate of reaction at 3 seconds (1 Point)

1

(Decreasing the rate of reaction means less frequent and/or fewer successful collisions).

Why does the powdering of calcium carbonate increase the rate of its reaction with an acid?

1

Hint look at the state symbols

1

A gas syringe is better than collecting over water as the less _______ dioxide dissolves in the water.

1

This method of adding the acid to the marble chips is better as the _______ does not escape while the bung is being added.

1

If the water in the trough is saturated with sodium carbonate _______ dioxide will not dissolve.
