Consider the following data for the decomposition reaction:

$\backslash$table$[[$Time $(sec),$Concentration of $H_2{O}_2(mo\frac{l}{L}),$Log of Concentration$],[0,2\mathrm{.}32,0\mathrm{.}37],[300,1\mathrm{.}86,0\mathrm{.}27],[600,1\mathrm{.}49,0\mathrm{.}17],[1200,0\mathrm{.}98,-0\mathrm{.}01],[1800,0\mathrm{.}62,-0\mathrm{.}21],[3000,0\mathrm{.}25,-0\mathrm{.}60]]$

a$)$ Prepare a graph of concentration versus time. This graph must be done by hand on graph paper.

b$)$ Prepare a graph of $log$ of concentration versus time. This graph may be done on the computer or by hand on graph paper. If you plot the graph using the computer, you must show grids.

c$)$ Which of these two graphs $($a or b$)$ is a straight line?

d$)$ Determine the equation for the straight line produced in $"a"$ or $"b".$
