Reaction time biology practical
WebThe practical includes two parts, which can be used to show how the rate of reaction is affected by surface area and concentration respectively. The experiment is probably most suited to younger students or groups of students who do not need to be given the details of the reaction itself. It is difficult to relate the rate back to the equation. WebReaction time is the time taken to respond to a stimulus; reactions are usually very quick responses typically taking less than a second to occur Reaction time can be affected by …

WebAt each temperature students should plot a graph of volume of oxygen produced against time. The initial rate of reaction can be determined from these graphs by taking the gradient of the graph at the start of the reaction after time zero. A second graph of initial rate of reaction versus temperature can = temperature.
