Determining activation energy graphically
Did you know?
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.

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. maryhill health centreWebThe energy required to reach this transition state is called activation energy. ...
