I'm stuck on a question on photochemical reactions. I've attached a screenshot of it below, and I think I have worked out the first part of the question which asks for an expression for the quantum yield of the reaction which Ive written at the bottom of the screenshot. But I don't know how to show that the data is consistent with the scheme.
I first thought about finding an equation based of the quantum yield which shows a linear relationship by plotting the reciprocal of the quantum yield against concentration, but this didn't give me a straight line. However, I do get a straight line if I do the reciprocal of the quantum yield against the reciprocal of the concentration, but I can’t get my quantum yield expression to do this (i.e: I can't get an equation of the form y = mx + c with 'y' as the reciprocal of the quantum yield and 'x' as the reciprocal of concentration).
I was wondering how I could go about proving the data is consistent with the data. Any help will be greatly appreciated.
