How does Activation Energy Affect Reaction Rate?

Click For Summary
SUMMARY

The activation energy for the reaction 2N2O5 (g) → 2N2O4 (g) + O2 (g) is established at 103 kJ/mol. To determine the temperature at which the reaction rate is 80.0 times greater than at 300 K, the Arrhenius equation must be utilized. The gas constant is specified as 8.314 J/mol*K. Clarification is needed regarding the temperature unit, as the discussion raises the possibility of a misinterpretation between Celsius and Kelvin.

[SOLVED] Activation Energy related to rate.

The activation energy for the reaction : 2N_{2}O_{5} (g) \rightarrow 2N_{2}O_{4} (g) + O{2} (g), is 103 kJ/mol.

The gas constant is 8.314 J/mol*K
Using only information given in this problem calculate the temperature at which the rate of the reaction is 80.0 times greater than it is at 300.0 degrees C (Notice that the given information concerns rates, not rate constants.)


I'm not really sure how do go about this question. do I still use Arrhenius's Equation?

any help would be greatly appreciated. thanks

Yes, you can use the Arrhenius equation. Did you really mean 300 C? Are you sure it isn't 300 K? As far as I know, this very complicated first-order reaction was only studied over the temperature range 0 C to 123 C but I may be wrong. Please check.
