Question

The compound 1,1-difluoroethane decomposes at elevated temperatures to give fluoroethylene and hydrogen fluoride according to the equation: 

CH3CHF2(g) -> CH2CHF(g) + HF(g)

At 460 K, the rate constant for this reaction is k = 5.8 ×× 10–6 s–1 and the activation energy is Ea = 265 kJ/mol. What is the frequency factor for this reaction?  

At what temperature would the reaction proceed with a rate four times faster than at 460 K? ____K
