Question

CHEM1212 Chapter 12 Kinetics Excel Project


1. The table below gives concentration of H2O2 as a

function of time for the decomposition of hydrogen peroxide at 25°C:

2 H2O2 (aq) → 2 H2O (l) + O2 (g)

Time (hr): 0 6 12 18 24

[H2O2] (M): 1.0000 0.5000 0.2500 0.1250 0.0625


a) Plot [H2O2] vs. Time (hr). Label the axes and give title as "Question #1 - Zero Order Test." Fit a straight line through the points and display the equation and R-Squared (RSQ) value on the graph. (Print out the Graph by itself in Landscape Format on a single piece of paper) DO NOT Print out spreadsheet


b) Plot ln [H2O2] vs. Time (hr). Label the axes and give title as "Question #1 - First Order Test." Fit a straight line through the points and display the equation and R-Squared (RSQ) value on the graph. (Print out the Graph by itself in Landscape Format on a single piece of paper) DO NOT Print out spreadsheet


c) Plot 1 / [H2O2] vs. Time (hr). Label the axes and give title as "Question #1 - Second Order Test." Fit a straight line through the points and display the equation and the R-Square (RSQ) value on the graph. (Print out the Graph by itself in Landscape Format on a single piece of paper) DO NOT Print out spreadsheet


d) Determine the order of reaction with respect to A and the rate constant with appropriate units. Use a textbox in Excel to write the order and the rate constant with appropriate units on the appropriate graph. (Print out the appropriate Graph with the Rate Constant)
