Similarities -
Stretching band at 1780 cm-l (medium intensity ) and band at 1701 cm-l is due to -C=O similar to both spectra.
Difference -
Stretching band at 1476.99 cm-l to 1654.10 cm -l are missing in maleic anhydride and present in spectra.
b) Yes, this spectra clears that structure of product is combination of two reactant . Because presence of carbonyl region of carboxylic acid and anhydride indicate to two reactant and other peaks cementing that.
