A reaction with one reactant that is in the first-order takes place in the liquid phase in an isothermal CSTR. The feed which has 1 mole reactant/L enters at a rate of 15 liters per minute. Suggesting that the aimed conversion is 90% and the reactor has a volume of 150 L, determine the temperature at which the reactor should be operated. Additional data: k at 303K = 0.80 min^-1, ratio of activation energy and gas constant = 799. (Hint: the specific answer is between 300 and 350 K)
