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

1. Answer;

= 5.4×10-6 g AgBr

Explanation;

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

2. Answer and explanation;

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

Energy factor; enough energy in the collision for the formation of an activated complex, where bonds are breaking and new ones forming. When temperature is increased, a greater number of molecular collisions possess enough energy to activate the reaction.Frequency of collisions increases; an increase in temperature makes particles move faster and collide more frequently, increasing the possibility of a reaction be-tween them.

More important factor; Energy factor is more important.

Are there any options?

I’m not sure what your trying to say here.. can you clarify again?
