Order and Half-life Equations
... The order (and thus the rate law) is determined by linear regression analysis of three graphs. The graph with the best straight line (r2 closest to 1) determines the order. Note that the absolute value of the slope is the value of the rate constant. The graphs (y vs x): - Zeroeth Order: [A] vs. t ha ...

... first-order rate of consumption of benzyl alcohol, therefore O2 is integral to the kinetics of the reaction (eqn. 3). This result differs significantly from previous work by Mizuno et al, where O2 was found to have no effect on the rate of reaction (zero order) when it was performed in a batch react ...
