4.6: Activation Energy and Rate - Chemistry LibreTexts
WebA typical plot used to calculate the activation energy from the Arrhenius equation. In this graph the gradient of the line is equal to -Ea/R. Extrapolation of the line to the y axis gives an intercept value of lnA. When the temperature is increased the term Ea/RT gets smaller. This means in turn, that the term e-Ea/RT gets bigger. WebIf the Arrhenius equation is applicable, you will get a negative slope, which will be equal to E/R where E is the activation energy in J/mol and R is the universal gas constant, 8,314 … WebSo just solve for the activation energy. So we have 3.221 times 8.314 and then we need to divide that by 1.67 times 10 to the -4. And so we get an activation energy of approximately, that would be 160 kJ/mol. We need our answer in kJ/mol and not J/mol, so we'll say approximately 160 kJ/mol here. dallastown borough dallastown pa
