Nitrogen dioxide is one of the many oxides of nitrogen (often collectively called "NOX") that are of interest to atmospheric chemistry. It can react with itself to form another form of NOx, dinitrogen tetroxide. A chemical engineer studying this reaction fills a 125 L tank with 17. mol of nitrogen it contains 9.4 mol of nitrogen dioxide gas. dioxide gas. When the mixture has come to equilibrium he determines that to come The engineer then adds another 5.7 mol of nitrogen dioxide, and allows the mixture after equilibrium is reached the second time. Round your answer to 2 significant digits. to equilibrium again. Calculate the moles of dinitrogen tetroxide

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…
