Q+ 1. The heat evolved or absorbed or absorbed when reactants react completely to produce produets is called 2. The heat content change in a chemical reaction is the same whether it takes place in one or several stages, provided the temperature and either pressure or volume remain constant is called 3- The slope of a plot of AG against T gives - 4- Debye showed that at lower temperature about - 258 *C, the heat capacity of a solid may be expressed as 5- The clausius - clapeyron equation in general form is - 6- The value of dP/ST obtained will be in callc.c./deg and in order to convert the value of dP/dT to more convenient unit of atm/deg: the following factor is used 7. If the solution obeys Raouli's law, the activity of any component is to mole fraction of that component in the solution. 8- The excess thermodynamic function may be defined as 9. The entropy of mixing for regular solution is same as for an ideal solution and is equal to 16- For an electrochemical cell operating under reversible conditions, the term Ir in galvanic cell is called 25 Mark
