The curve below shows how the volume of oxygen evolved varies
with time when 50 cm3 of a 2.0 mol dm–3 solution of hydrogen
peroxide, H2O2, decomposes at 298 K.
Sketch curves, on the above axes, to illustrate how the volume
of oxygen evolved would change with time if the experiment
was repeated at 298 K using the following.
(i) 100 cm3 of a 1.0 mol dm–3 solution of H2O2. Label this
curve X.
ii) 25 cm3 of a 2.0 mol dm–3 solution of H2O2 in the
presence of a catalyst.
