I agree, well done.

So is this method only suitable for finding the rate of reaction, how about finding the activation enthalpy? The procedure looks at the amount of titrant required for colourless endpoint at 60 degrees and at room temperature

Well, what information would you need to know in order to calculate Ea?

You would need k from the graph .. but two temperatures are used to get a and x I cannot see how I would use the equation.

Repeat with a different temperature instead of the 60 degrees celsius and use the equation above?
