How do I do this

In a series of experiments on the decomposition of dinitrogen pentoxide, \( \text{N}_2\text{O}_5 \), rate constants were determined at two different temperatures. At 35°C, the rate constant was \( 1.4 \times 10^{-4} \, \text{s}^{-1} \); at 45°C, the rate constant was \( 5.0 \times 10^{-4} \, \text{s}^{-1} \). a. What is the activation energy for this reaction? (Enter your answer to two significant figures.) Activation energy = \_\_\_\_\_\_ J/mol b. What is the value of the rate constant at 55°C? (Enter your answer to two significant figures.) Rate constant = \_\_\_\_\_\_ \(\text{s}^{-1}\) There are no graphs or diagrams in this text.
