Calculate values for the natural logarithm of [H2O2] using an appropriate formula. Time H2O2(M) LN [H2O2] 0 0.862 120 0.556 240 0.394 360 0.246 480 0.149 b. Create a graph of [H2O2] versus time. Use the Scatter chart type and use the subtype that connect the points with a line. c. Create a graph of LN(H2O2) versus time. Use the scatter chart type and use the subtype that does not connect the points with a line. Instead, insert a trendline (linear fit) and display the equation of the line on the graph. d. Using the trendline equation, calculate the natural log of concentration (LN[H2O2] corresponding to a time elapsed of 200 seconds. From that value, calculate the molar concentration of H2O2 at 200 seconds

Step 4 you need to clean off the MgO from the surface of the Mg metal. What would happen to the amount of H2 that you would produce if you did NOT clean off the Mg0? Would the amount of H2 increase, decrease, or stay the same. Be sure to explain why and justify your answer.
I have my graph made but need to do the following but do not remember how. "Use graph paper in lab book to plot moles S2O82- consumed versus time in seconds and fit with a line of best fit.""To determine the slope of your line do not use any of the data points from your data, use 2 points on your straight line.""Units of rate are M/s so you must calculate rate from the slope of your line (mol/s)" The first picture is the graph, using the seconds and moles from the second picture.
