If a reaction begins with a mixture of NO2 and O2 at partial pressures of 1.00 atm each, the reaction will be spontaneous until some N2O5 forms in the mixture. What is the maximum partial pressure of N2O5 that can build up before the reaction ceases to be spontaneous? PN2O5=

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
