A fixed conversion of a given batch of feed takes 5 hours

After every 5 hours, reactor is being filled with the feed

Cent per cent conversion can be achieved in at least 5 hours

Five reactor volumes of feed (at specified conditions) are being fed into the reactor per hour

Back-mix reactor

Plug-flow reactor

Batch reactor

Fixed bed reactor

Half the specific rate constant

Proportional to the initial concentration of reactants

Dependent on initial concentration of the reactants

Always the same irrespective of the reaction

Is independent of pressure

Increases with pressure

Decreases with pressure

Increases /decreases with pressure depending on the stoichiometric co-efficients of the reaction

Maximum at the centre of the reactor

Maximum at the exit of the reactor

Maximum at the inlet of the reactor

Constant throughout the reactor
