state why in lab,we have to count initial reading of maleic acid at 2.0g ,and initial reading of filter paper? why fumaric acid have higher melting point at 300 degree celsius? is it ideal? and why maleic acid have less melting point 155 degree celsius. why is percentage yield in conversion of maleic acid to fumeric acid at 25.315%? what is the reason we use yield in this experiment.Assume that equilibrium concentrations were achieved in the experiment.Which acid is stable. Explain all.
