Answer:
0.100 M AlCl₃
Explanation:
The variation of boiling point by the addition of a nonvolatile solute is called ebullioscopy, and the temperature variation is calculated by:
ΔT = W.i
Where W = nsolute/msolvent, and i is the Van't Hoff factor. Because all the substances have the same molarity, n is equal for all of them.
i = final particles/initial particles
C₆H₁₂O₆ don't dissociate, so final particles = initial particles => i = 1;
AlCl₃ dissociates at Al⁺³ and 3Cl⁻, so has 4 final particles and 1 initial particle, i = 4/1 = 4;
NaCl dissociates at Na⁺ and Cl⁻ so has 2 final particles and 1 initial particle, i = 2/1 = 2;
MgCl₂ dissociates at Mg⁺² and 2Cl⁻, so has 3 final particles and 1 initial particle, i = 3/1 = 3.
So, the solution with AlCl₃ will have the highest ΔT, and because of that the highest boiling point.
Answer:
Rubidium Acetate
Explanation:
Rb is Rubidium C2H3O2 is acetate
Actually the rate of reaction can be shown as:
R = k [A]^x [B]^y
The rate of reaction can be determined with help of order of reaction which is an experimental quantity and the order can be determined experimentally.
Hence for the rate of reaction crystall violet depends on order of crystall violet and mostly the order of crystall violet is 1 and thus on doubling the concentration, the rate of reaction gets doubles.
The molar mass is 286.94 g/mol
