When discussing the Arrhenius equation and chemical / enzyme kinetics, which of the following statements is incorrect ? A. A cat

alyst lowers the activation energy of a reaction B. A high activation energy signifies that the rate constant depends strongly on temperature C. A negative activation energy indicates that the rate increases as the temperature is raised D. The activation energy, the parameter Ea in the Arrhenius equation, is the minimum energy that a molecular encounter needs in order to result in a reaction E. If a reaction has zero activation energy, its rate is independent of temperature

What is the final volume (l) of a 10.0 l system that has the pressure quartered?
mihalych1998 [28]
According to Boyle's Law, P1V1 = P2V2

where P1 and V1 are initial pressure and volume respectively. P2 and V2 are final pressure and volume receptively.

Given: P2 = 4 P1 and V1 = 10.0l

∴ V2 = 2.5 l

Answer: Final volume of system is 2.5 l

A 0.300 m solution of hcl is prepared by adding some 1.50 m hcl to a 500 ml volumetric flask and diluting to the mark with deion
liberstina [14]
In dilution we add distilled water to decrease the concentration of required sample from high concentration to lower concentration
The law used for dilution:
M₁V₁]Before dilution = M₂V₂] After dilution
M₁ = 1.5 M
V₁ = ?
M₂ = 0.3 M
V₂ = 500 ml
1.5 * V₁ = 0.3 * 500 ml
so V₁ = 100 ml and it completed to 500 ml using 400 ml deionized water
