Once you have A, you can plug it into the equation to solve for k at the temperature of 273 K. Start by setting up the initial calculation: k = …
WebA best fit line and determination of an equation yields y=1*10-12 *e 0.12x. This equation is very similar to Arrhenius’ equation. Then, the data of ln k vs 1/temperature was graphed and a best fit linear line was used. The … WebThe Arrhenius equation allows us to calculate activation energies if the rate constant is known, or vice versa. As well, it mathematically expresses the relationships we established earlier: as activation energy term E a increases, the rate constant k decreases and therefore the rate of reaction decreases. Determining the Activation Energy ...
