Consider the equations below. CH, (9) →C(s)+ 2H, (9) AH, – 74.6 kJ
C(s) + 2CI,(9)→ cCi, () AH, =-95.7 kJ
2H,(g) + 2CI,(9)→ 4HCI(G) AH, =-184.6 kJ
CH, (9) + 4Ca, (9) → Ca,(9) + 4HCI(9) AH, =-205.7 kJ

when the volume of gas is   changed from   717.73 ml   to 852 ml   the temperature will   change   from 315   c to 452   c

    calculation

this is calculated using the charles law formula

that is,   v1/t1 = v2/t2

          v1=?

        t1 = 315 c   into   kelvin = 315 +273 = 588 k

        v2 = 852   ml

        t2 = 425c + 273 =698 k

make v1   the subject of the formula ( by   multiplying both side by t1)

  v1=( v2 xt1) / t2

v1= (852 ml   x 588 k)/ 698 k= 717.73 ml
