The enthalpy of fusion for benzene (c6h6, 78.0 g/mol) is 127.40 kj/kg, and its melting point is 5.5°c. what is the entropy change when 1 mole of benzene melts at 5.5°c? (show all unit conversions and write out all equations)

35.662 J/K is the entropy change when 1 mole of benzene melts at 5.5°C

Explanation:

The enthalpy of fusion for benzene =

Molar mass of benzene = 78.0 g/mol

Or can be written as 1 mole of benzene = 78.0 g

1 g of benzene  =

= 127.40 kJ/kg=127.40 kJ/1000 g (1kg = 1000 g)

= 9.9372 kJ/mol = 9937.2 J /mol

The entropy change when 1 mole of benzene melts at 5.5°C:

T = 5.5°C = 278.65 K

answer; capital earns interest; entrepreneurship receives a profit or incurs a loss;

a). in this case, dh> 0 and sd> 0. if t becomes larger, the term "-tds" will become more negative. at some point, it is possible that -dts will be more negative than the dh is positive, and the reaction will become spontaneous. this is probably the correct answer, but you should look at all of the other possibilities and make sure of that.
