The initial reaction rate for elementary reaction 2A +B 4C was measured as a function of temperature when the concentration of A was 3 M
The initial reaction rate for elementary reaction 2A +B 4C was measured as a function of temperature when the concentration of A was 3 M and B was 2 M. Calculate the activation energy.
-rA (mol/dm3.s) | 0.002 | 0.046 | 0.72 | 8.33 |
T (K) | 300 | 320 | 340 | 360 |
Explanation: Write the reaction rate equation assuming elementary rxn. Solve the question by finding the kA values from the Rxn velocity equation and creating a table. You can find the activation energy value by any numerical method you want (drawing graphs, using excel, establishing a proportion, etc.).
