can you please answer this question for me.
thanks in advance
1-Chloropropane was hydrolysed by an aqueous potassium hydroxide solution.
C3H7Cl + KOH → C3H7OH + KCl
During the reaction, the reactant potassium hydroxide is used up. Samples of the reaction mixture were drawn off at regular time intervals and analysed by titration with standard hydrochloric acid to find out the concentration of KOH.
The results are given in the table below:
Time / s
Concentration of OH- / mol dm-3
From the above information, Plot a Concentration of OH- (mol dm-3) against Time (s) graph. The graph MUST be a hand drawn (plotted) graph.
Select 4 suitable points along your graph [see part (a)] and draw tangents to find the rates. Construct a table of “Rate” against “Concentration”. Note: The rates need to be calculated and the calculations shown.
Plot a graph of Rate against Concentration of OH-. The graph MUST be a hand drawn (plotted) graph.
From your graph in part (c) deduce the Order of Reactionwith respect to OH- (hydroxide ions).
Write a rate equation with respect to concentration of hydroxide ions.
Calculate the rate constant k from the gradient of the graph, drawn in part (c). Show and explain your working.
