Problem- The reaction, C2H5Cl C2H4 + HCl, follows first-order kinetics and has an activation energy of 237 kJ mol-1. At 477 °C, k = 0.000904 s-1. Find the temperature (in °C) at which half-live will be 9.96 min? Round your answer to 3 significant figures.
Please take care to answer the question as mark are equally granted for each point
