The orchid Ophrys ensures pollination by mimicking the appearance and scent of a female bee. Male bees, attracted to the orchid, attempt to mate with it (pseudocopulation) and inadvertently carry pollen to other flowers.
A certain reaction is 50 complete in 20 minutes at 300 K and the same reaction is 50 complete in 5 minutes at 350 K. Calculate the activation energy if it is a first order reaction. Given: \[ R = 8.314 \, \text{J K}^{-1} \, \text{mol}^{-1}, \quad \log 4 = 0.602 \]
