Graphically determine activation energy

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.
