Answer: It increases the reaction rate.
Step-by-step explanation:
The particles gain kinetic energy.
Vol.250 before its to much pressure
Boiling Point, Melting Point, Viscosity, Surface Tension. Decrease: Vapor Pressure.

28%
Explanation:
mass of solute(KBr) = 3.73g
mass of solvent(H2O) = 131g
mass of solution = mass of solute + mass of solvent
= 3.73 + 131
= 134.73g

Iodine is going to form anions capturing electrons from some other element more electropositive
