Because of the thing, that we had to put the pressure sensor manually in the tube and every time the rate of this action depended on the rate of human reaction and every time the human reaction was not the same, so, it could make inaccurate initial rate

More modern apparatus has to be used in order to avoid such errors. Because the pressure has to be measured as soon as hits the surface of hydrogen peroxide.

Every time we tried to use a certain shape of the piece of potato but every new piece we cut manually which of course lead to the errors in the certainty of the pieces.

We can use some technology which can cut identically certain pieces with the same surface area. In order to avoid errors and uncertainty on the results.

Some graphs had no time to continue after the point of saturation and we don’t even know how this graph would continue and will it continue as a normal graph of the effect of substrate concentration on the rate of the reaction or not.

We should do each experiment longer, until the graph reaches the point of saturation and more in order to see that it would continue as we predicted.

We were doing this experiment during

some days and on every day the

environmental and thus the

temperature of the room was different

and this could influence on the rate as

well and at the end we would get

Inaccurate results.

We should spend much time in one day and do this experiment in the same room and in the same day.
