Solid sodium carbonate reactk88+l t2s b e+hvc1a ,fyxfhg0pyz:9 bs with excd*inkpy; xgij:6 b2nw-2r5ee ess nitric acid of 0.10 mol dm$^{-3}$ as shown in the equation below:
$Na_2CO_3$(s) + 2$HNO_3$(aq)→$H_2O$(l) + $CO_2$(g) + 2$NaNO_3$(aq)
1.State a method to measure the rate of reaction other than measuring the volume of gas collected.
2.1.Sketch a graph to show the volume of gas produced over time.
2.2.Explain the shape of your graph using the collision theory.
$CO_2$ is produced in the reaction; hence, the volume of $CO_2$ over time.
3.On the same graph as in part(bi), sketch another line to show the volume of gas collected over time at a concentration of 0.05 mol dm$^{-3}$ of nitric acid and label it as X.
4.Suggest and describe a factor other than the concentration that can affect the rate of the above reaction.
