Answer 1

Explanation:

energy of the gas?

3. Fill in the blanks.

(i) The reaction which has a natural urge to proceed of its own is called

............. reaction.

(ii) In the freeze of water to ice enthalpy.......

(iii) The decrease in ........... ............... is equal to the useful work done by the

system

(iv) If is.

the teaction does not occur in the forward direction.

4. Calculate the enthalpy of formation of methane from the following data. (2)

C(s) + O 2 (g)CO 2 (g); r H 0= - 393.5 kJ

2H 2 (g) + O2 (g) 2H 2 O @rH 0 = - 571.8 kJ

CH 4 (g) +20 2 (g) CO 2 (g) + 2H 20 (1) r H 0 = - 890.3 kJ

5. Calculate the enthalpy of formation of carbon disulphide given that the

enthalpy of combustion of carbon disulphide is 110.2 kJ mol-1 and those of

sulphur and carbon are 297.4 kJ and 394.5 kJ/g atom respectively. (2)

6. Calculate the enthalpy of formation of acetic acid (CH 3 COOH) if its

enthalpy of combustion is -867 kJ mol -1. The enthalpies of formation of CO2
