Identify the proper form of the equilibrium-constant expression for the equation n2(g)+o2(g)⇌2no(g) view available hint(s) identify the proper form of the equilibrium-constant expression for the equation k=[no][n2][o2] k=[no]2[n2][o2] k=[n2][o2][no]2 k=2[no][n2][o2]

The proper equilibrium-constant expression for the equation is:

Explanation:

Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios. It is expressed as

An equilibrium-constant expression for the equation is given by:

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
