Determine the entropy change when 1.80 mol of hbr(g) condenses at atmospheric pressure?

Entropy change = -168.3 J/mol-K

Explanation:

The entropy change is expressed as:

For HBr, the enthalpy of condensation = -19.27 kJ/mol

Temperature T = -67 C = 273 - 67 = 206 K

Therefore, the entropy change when 1 mol of HBr condenses is:

=

Thus for the given 1.80 mol of HBr the entropy change would be:

the ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (uvr) from the sun, protecting life on earth from its potentially harmful effects. when the sky is clear, there is an inverse relationship between stratospheric ozone and solar uvr measured at the earth's surface.
