Use equations A and B to determine AH for the following reaction: 2CO(g) + 2NO(g) → 2CO2(g) + N2 (9)
AH = ??
A. 2CO(g) + O2(g) → 2CO2(g)
AH = -566.0 kJ
B. N2 (g) + O2(g) → 2NO(g)
AH = -180.6 kJ
-746.6 kJ
+746.6 kJ
-385.4 kJ
+385.5 kJ

what's the

let that person have a turn to speak : )

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
