AboutPressCopyrightContact... 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.

"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. " - Reaction time biology practical

Web10.2.4 Response time. Response time is defined as the time at which the pH concentration in a solution is changed on contact with a pH sensor and a reference electrode has reached 95% (or 90%) of the final value. The response time is reported as t95% or t90% in seconds or minutes. In many investigations, the response time of the overall ... WebPolymerase chain reaction, or PCR, is a technique to make many copies of a specific DNA region in vitro (in a test tube rather than an organism). PCR relies on a thermostable DNA polymerase, Taq polymerase, and requires DNA primers designed specifically for the DNA region of interest. In PCR, the reaction is repeatedly cycled through a series ...
