The graph shows the amount of a gaseous product formed over time during two trials of a reaction. A different concentration of a reactant was used during each trial while other factors were kept constant. (see graph)

Which of the following statements explains which trial has a higher concentration of the reactant?

Trial 1, because the final amount of product formed is higher.

Trial 1, because this reaction lasted for a longer duration than Trial 2.

Trial 2, because this reaction was initially fast and slowed down later.

Trial 2, because the amount of product formed per unit time is higher.

Trial 2, because the amount of product formed per unit time is higher.

Explanation:

I have the same question

thats how its supposed to be

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
