At lower concentrations (from 0.1 to 1.0) _______________ the concentration _____________ the time taken to collect 10cm3 of gas.

At concentrations of 0.1 to 0.5 adding a catalyst _____________ the time taken to collect 10cm3 of gas.

At concentrations of 1.0 and 2.0 adding a catalyst _____________ change the time taken to collect 10cm3 of gas.

Higher concentrations will _____________ the time taken to collect 10cm3 of gas unless there is already an excess of hydrogen ions around the zinc pieces.

At high concentrations a catalyst is not needed as there are already enough hydrogen ion particles with enough energy to exceed the _______________ energy.
