WebAnd our temperatures are 510 K. Let me go ahead and change colors here. So we're looking for k1 and k2 at 470 and 510. So let's go back up here to the table. So 470, that was T1. And so this would be the value for the first rate constant, 5.79 times 10 to the -5. And then T2 was 510, and so this would be our second rate constant here. WebOrder of reaction from initial rate. The progress of the reaction can be followed by measuring the initial rates of the reaction using various initial concentrations of each reactant; These rates can then be plotted against time in a rate-time graph; In a zero-order reaction the rate doesn’t depend on the concentration of the reactant. The rate of the …
