After plotting out various graphs, we came up with the 'correct' one and from there, we could conclude whether our hypothesis was correct or wrong. Our first hypothesis is correct as we can see that there is a trend of better diffusion with the decreasing rate of the molecular weight. Hence we can conclude that there is a link between molecular weight and rate of diffusion. Whereas, our second hypothesis was wrong, there was no detectable link between both diffusion and vapor pressure. Hence we can conclude that vapor pressure does not affect the rate of diffusion of soap.
