Plot a graph of concentrations and absorption rates using known concentrations of KMnO4 Then set up colorimeter and place unknown sample and see what it's absorption rate is Use the absorption rate on the graph and go across until you find the concentration

What did people say for effect of increasing pressure on emf
I said increase as would be a in increase rate of reaction - I don't think reaction was reversible so le chateliers principle would be irrelevant? May be wrong
nah second one asked for the reaction of the element (so Na + H2O) & the first asked for the reaction of the oxide of the element (P4O10 + H2O). i think
MnO4- ions are purple Filter light so only frequencies absorbed by the sample are let through. The more concentrated the solution is, the less light it will let through. Plot calibration graph with known concentrations and their absorbances. Use line of best fit to find concentration.
