RoseMarie Gallagher and Paul Ingram Solutions for Chapter: The Speed of a Reaction, Exercise 1: Exercise 1

Here are some reactions that take place in the home. Put them in order of decreasing rate (the fastest one first). 

a. raw egg changing to a hard-boiled egg

b. fruit going rotten

c. cooking gas-burning

d. bread baking

e. a metal tin rusting

Which of these rates of travel is slowest?

$5$kilometres per second

$20$kilometres per minute

$60$kilometres per hour

Suppose you had to measure the rate at which zinc is used up in the given reaction. Which of these units would be suitable? Explain your choice. 

a. a litres per minute

b. grams per minute

c. centimetres per minute

Iron reacts with sulphuric acid like this:

$\mathrm{Fe}\left(\mathrm{s}\right) + {\mathrm{H}}_2{\mathrm{SO}}_4\left(\mathrm{aq}\right) \to {\mathrm{FeSO}}_4\left(\mathrm{aq}\right) + {\mathrm{H}}_2\left(\mathrm{g}\right)$

Write a word equation for this reaction.

Iron reacts with sulphuric acid like this:

$\mathrm{Fe}\left(\mathrm{s}\right) + {\mathrm{H}}_2{\mathrm{SO}}_4\left(\mathrm{aq}\right) \to {\mathrm{FeSO}}_4\left(\mathrm{aq}\right) + {\mathrm{H}}_2\left(\mathrm{g}\right)$

Write down four different ways in which the rate of the reaction could be measured.
