\"Picture30\"<\/td>\nIn this question, the term average can be confusing.\u00a0\u00a0We call it an average rate because\u00a0 the rate is changing as the reaction proceeds\u00a0in the first\u00a015 minutes of the reaction, as shown by the changes in the values.\u00a0 ( A constant rate would produce a constant change).<\/p>\n

The average rate is simply calculated in these circumstance by examining the change in quantity\u00a0and dividing that by the time taken.<\/p>\n

\"Picture31\"<\/a><\/td>\n\u00a0For this question, it is important that you consider the starting conditions of any chemical reaction.\u00a0 All reactants are at their highest concentrations.\u00a0 As the reaction proceeds, the concentration of the reaction will decrease.\u00a0 This will allow you to establish if the rate rises or falls.<\/td>\n<\/tr>\n
\"Picture32\"<\/a><\/td>\n\u00a0You know from the graph the starting mass, you know the final mass – so you can calculate how much has been used by the end of the reaction\u00a0 [that the line falls to a straight horizontal line indicates the reaction has reached an end point].<\/p>\n

Read from the graph when half this mass has been lost.\u00a0 This time would be the half life.<\/td>\n<\/tr>\n

\"Picture33\"<\/a><\/td>\nAll mass lost from the reaction is due to the\u00a0production<\/strong><\/em> of carbon dioxide gas.\u00a0 Your graph must reflect your understanding of the change in rate with time.<\/p>\n
