Answer» Correct option is (a) –ri = \(\FRAC{1}{RT}\frac{dpi}{dt} \) EXPLANATION: The design equation for batch SYSTEM is –ri = \(\frac{1}{V}\frac{dNi}{dt}.\) For constant VOLUME system –ri = \(\frac{d(\frac{NI}{V})}{dt} = \frac{dCi}{dt}\) where C = p/RT. Hence, –ri = \(\frac{1}{RT}\frac{dpi}{dt}. \)
