Answer all questions in the spaces provided. 
0 1This question is about rates of reaction. 
Figure 1 shows apparatus used to measure the rate of reaction when an acid reacts 
with an excess of solid sodium hydrogencarbonate, NaHCO3 
When different monoprotic organic acids are used, the rates at which gas escapes 
can be used to compare the strengths of the acids. 
A timer is started when the NaHCO3 is added to the acid and 
the mass of...
