An equimolar liquid mixture of n-pentane and n-hexane at 25°C is fed continuously to a single-stage evaporator at a rate of 980 mol/s. Both the liquid and vapor streams leaving the evaporator are at 84.0°C. The vapor contains 72.5 mole% n-hexane and the liquid contains 38.0 mole% n-hexane. Estimate the required rate of heat transfer to or from the evaporator in kW. Display all values in three decimal places/significant figures.
