Consider the following reaction at constant P. Use the information here to determine the value of Ssurr at 355 K. Predict whether or not this reaction will be spontaneous at this temperature. Question 7 options: Ssurr = +114 kJ/K, reaction is spontaneous Ssurr = +114 kJ/K, reaction is not spontaneous Ssurr = +321 J/K, reaction is spontaneous Ssurr = -321 J/K, reaction is not spontaneous Ssurr = +321 J/K, it is not possible to predict the spontaneity of this reaction without more information.

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

the answer is c. nacl
