For the given reaction, sign of entropy change, nature of equilibrium mixture has to be given and also the reason for heating of reaction mixture has to be given. Concept introduction: Standard free energy change: Standard free energy change is measured by subtracting the product of temperature and standard entropy change from the standard enthalpy change of a system. ΔG o = ΔH o - TΔS o where, ΔG o - standard free energy change ΔH o - standard enthalpy change ΔS o - standard entropy change and T - temperature . Spontaneous process: The chemical or physical change can takes place by itself without the help of surroundings are called as spontaneous process.

The total number of carbons in the parent chain is incorrect. Review the reaction conditions including starting materials and/or
intermediate structures and recount the number of carbon atoms in the parent chain of your structure.

Using a cell of known pathlength b = 1.25115 x 10-3 cm, a water absorption spectrum was measured. The band at 1645 cm-1, assigned to the O-H bending, showed an absorbance, A, of 1.40.
a) Assuming that water density is 1.00 g/mL, calculate the water molar concentration c (hint: M= mole/L)
b) Calculate the molar absorptivity, a, of the 1645 cm-1 band
c) The transmitted light, I, can be written as I= Ioexp(-xb), where x is the absorption coefficient (sometimes designated as alpha), Io is the input light, and b is the cell pathlength. Prove that x= (ln10)*x*c
d) Calculate x for the 1645 cm-1 band
Convert 1.38 eV into wavelength (nm) and wavenumber (cm-1) (c = 2.998 x 108 m/s; h = 6.626 x 10-34 J*s).
