The reaction is complete when the syringe no longer moves to find the actual rate we plot a graph of volume of hydrogen (cm3) against time (seconds) // note: 1 the rate is not a constant throughout the reaction - it changes 2 the reaction is fastest at the start, gradually becoming slower as the reaction proceeds 3.
