Shifts to products.

Explanation:

the reaction is

If we add base (NaOH) to it, the base will react with the hydrogen ions decreasing the concentration of products. This will shift the equilibrium towards products.

As per Le-Chatelier's principle, if we apply any change to an equilibrium system, the system shifts in the direction where it can nullify the effect of stress applied. As we are decreasing the concentration of products the system will shift towards product to increase the concentration further.

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
