# Calculating the Rate Constant at a Different Temperature

CHEM-VEYB4Y

Consider the following reaction:

$$2 {{N}_{2} {O}_{5}}_{(g)} \rightarrow 4\ {N{O}_{2}}_{(g)} + {{O}_{2}}_{(g)}$$​

At $45 °C$, the rate constant is $4.8 \times {10}^{-4} \frac{1}{s}$. The activation energy for the reaction, $E_a$, is $104\ kJ/mol$.

What is the rate constant when the temperature is $55 °C$?
