Interpretation Introduction

Interpretation:

Between 00C and 1000C, the heat capacity of Hg(I) is given by CP,m (Hg,I) J-1K-mol= 30.093 – 4.944 × 10-3TK . The value of ΔΗ and ΔS needs to be calculated, if 2.25 moles of Hg(I) are raised in temperature from 0.000C to 88.00C at constant P.

Concept Introduction :

Enthalpy is known as the sum of internal energy and product of pressure andvolume provided by the below equation:

  H=U+PV .

When the procedure happens at constant pressure, the evolved heat is equal to the change in enthalpy.

The entropy of a system can’t increase in a reversible adiabatic procedure.
