How many grams of silver bromide agbr can be dissolved in 50 milliliters of water? changing the temperature and no other conditions changes the rates of most chemical reactions. two factors are commonly cited as accounting for the increased rate of chemical reaction as the temperature is increased. state briefly and discuss the two factors. which of the two is more important

= 5.4×10-6 g AgBr

AgBr(s) → Ag+(aq) + Br-(aq)Ksp = 3.3×10^-13

[Ag+][Br-] = Ksp = 3.3×10^-13 = X²

X = 5.7×10^-7 M = [Ag+] = mol/L AgBr that dissolve

1 mole of AgBr = 187.8 g

Therefore;

= 0.05 L × (5.7 × 10^-7 mol/L) × (187.8 g /mol)

= 5.4×10-6 g AgBr

The two factors that accounts for increased rate of chemical reaction when temperature is increased are:

More important factor; Energy factor is more important.

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
