a 1st order reaction graphs between t1/2 concentration i

WebA straight line first order reaction graph can be plotted: For determining if a reaction is first order reaction or not, plots the value of ln of concentration against time. If the plot comes out to be a straight line with downward (negative) slope, then the reaction is a first order reaction. We can also raise e.q.2 to the power e, WebHalf-Life Formula. It is important to note that the formula for the half-life of a reaction varies with the order of the reaction. For a zero-order reaction, the mathematical expression that can be employed to determine the half-life is: t1/2 = [R]0/2k. For a first-order reaction, the half-life is given by: t1/2 = 0.693/k. cholesterol pics
