(a)

Interpretation Introduction

Interpretation : The given chemical reactions should be identified as exothermic and endothermic.

Concept Introduction : An exothermic reaction can be defined as the chemical reaction which releases energy during the formation of product therefore the energy value must be written with product molecules in the balance chemical reaction.

An endothermic reaction can be defined as the chemical reaction which absorbs energy during the formation of product therefore the energy value must be written with reactant molecules in the balance chemical reaction.

The IR (infrared) spectra of two pure compounds (0.010 M compound A in solvent and 0.010 M compound B in solvent) are given. The pathlength of the cell is 1.00 cm. The y-axis in the spectra is transmittance rather than absorption, so that the wavenumbers at which there is a dip in the curve correspond to absorption peaks. A mixture of A and B in unknown concentrations gave a percent transmittance of 49.8% at 2976 cm¹ and 44.9% at 3030 cm-1 Wavenumber 0.010 M A 0.010 M B Unknown 3030 cm-1 35.0% 93.0% 44.9% 2976 cm-¹ 76.0% 42.0% 49.8% What are the concentrations of A and B in the unknown sample?
