Refer to Q3 and Q4 and estimate what is the maximum rate at which heat must be removed by the cooling coil (kcal/min) and at what time does this maximum occur? Using the following equation: Q ̇ = ΔHR kc2Ao VR

Refer to Q3 and Q4 and estimate what is the maximum rate at which heat must be removed by the cooling coil (kcal/min) and at what time does this maximum occur? Using the following equation: Q ̇ = ΔHR kc2Ao VR Correct Answer −828 kcal/min

The right-hand side is a maximum in absolute value (note it is a negative quantity) when cA is a maximum, which occurs for cA = cAo, giving Qmax = ΔHR kc2Ao VR = (−10 kcal/mol A) (0.01725 L/mol•min) (2.0 mol/L )2 (1200 L) = −828 kcal/min.
