An isothermal CSTR with a first order irreversible reaction A â> B (and rA[mol/(ft3*min)] = - 0.5 CA) has a constant flow rate of 29.0 ft^3/min. The reactor volume is 100 ft3. If the inlet concentration CAi is 7.3 moles/ft^3 at t = 0 and the initial outlet concentration CA is 2.3 moles/ft^3.

Required:
Determine the outlet concentration CA after t = 2.9 min
