Lab 05

The document contains graphs showing the conversion of a reactant over time. It analyzes the reaction order and determines that it follows second order kinetics based on the slope and R^2 value of the linear regression. Rate constants of -0.0002 and 0.0127 are reported for first and second order, respectively.
