i need help solving this step by step with all the calculations Below is a set of absorbance data that you have obtained while doing an experiment studying the diffusion of potassium permanganate into solutions of water. This diffusion experiment was conducted at three temperatures. I need help to Calculate the diffusion rates for each of these temperature conditions. Time (min) 4°C 22°C 37°C 0 0.024 0.108 0.081 5 0.048 0.144 0.221 10 0.069 0.196 0.321 15 0.088 0.224 0.424 20 0.086 0.234 0.580 25 0.089 0.248 0.683 Once you calculate your diffusion rates in standard notation and use 3 digits past the decimal point (Note that the last zero is considered to be a digit) Diffusion Rate 4°C = __________________ Diffusion Rate 22°C = _________________ Diffusion Rate 37°C = _________________ To show how you calculated the diffusion rates for these temperature - What absorbance values did you choose to…
