Answer» CORRECT answer is (d) t = CA0 \(\int_0^{XA} \frac{dXA}{-RA(1+XA εA)} \) Explanation: The varying volume in a BATCH reactor is given as V = V0 (1+XA εA) where εA is CALLED the fractional volume change of the SYSTEM. The above equation is substituted in the general batch reactor design equation.
