Hiya, I'm doing the OCR B Salter course for chemistry at A2, and for my investigation I've been given the kinetics of the Harcourt Essen reaction. One part of this is to work out the activation energy, and I've managed to get a value of 41.9kJ/mol. Apparently this is a pretty decent result but I was wondering if anyone knows what the standard value or true value is so I can compare my value to it, and where I could find a reliable source to reference it. Thanks to anyone who could help me out
