Arrhenius EquationThe variation of the rate constant with temperature can be expressed bythe Arrhenius Equation. The two-point form of this equation can be writtenas:(수)- (뉴Eak2Ink1T2where k2 and ki are the values of the rate constant at the Kelvintemperatures T2 and T, respectively, E, is the activation energy, and R isthe ideal gas constant.You may see slightly different, but equivalent, forms of this equation. It'seasy to confuse the different forms. They will all give the same result, butnot if you mix parts of one form with parts of another!Here are two more forms that you are likely to see.
