Pick out the wrong statement pertaining to space velocity of flow reactors.

The space velocity of 3 hr⁻¹ means that one third reactor volume of feed at specified conditions are being fed into the reactor
The unit of space velocity is (time)⁻¹
None of these
The space velocity of 3 hr⁻¹ means that three reactor volumes of feed at specified conditions are being fed into the reactor every hour

For a heterogeneous catalytic reaction

The surface of the catalyst does not play an important role during reaction
A relatively small amount of catalyst can cause the conversion of large amount of reactants which does not mean that catalyst concentration is important
Free energy of activation is lowered in the presence of catalyst, which remains unchanged at the end of reaction
The catalyst does not form an intermediate complex with the reactant
