Explanation:
Boiling is defined as a process in which vapor pressure of a liquid substance becomes equal to the atmospheric pressure.
During this change liquid and vapors remain in equilibrium and the equation for this change is as follows.
Therefore, when boiling takes place then average kinetic energy of particles in liquid phase equals to the average kinetic energy of particles in vapor phase.
Hence, we can increase the kinetic energy of particles in liquid phase by increasing the temperature because kinetic energy is directly proportional to temperature as follows.

Answer:
- False.
- False.
- True.
- True.
Explanation:
Hello, for each statement we state:
- An exponent of "2" means that if we double the concentration of the reactant the rate doubles as well.
FALSE because considering a rate law like:
The exponent of "2" powers the concentration to the second power, not doubles the rate law, thus, if C is 3, for k=1, r will be -9. On the other hand if the rate is like:
The rate will be -3, that is why the rate is not doubled when the "2" in concentration is present.
- Exponents in rate laws are based on the coefficients from the balanced equation.
FALSE because for nonelemental chemical reactions, the exponents do not match with each species' stoichiometric coefficients in the rate law.
- The rate constant, k, takes into account the effect of activation energy and temperature on the reaction.
TRUE, since the Arrhenius equation allows us to prove the effect of the activation energy and the temperature:
- Differential rate laws allow us to compare concentration and time.
TRUE as they are given like:
Best regards.
Answer:
2.76 × 10⁻¹¹
Explanation:
I don’t have access to the ALEKS Data resource, so I used a different source. The number may be different from yours.
1. Calculate the free energy of formation of CCl₄
C(s)+ 2Cl₂(g)→ CCl₄(g)
ΔG°/ mol·L⁻¹: 0 0 -65.3
ΔᵣG° = ΔG°f(products) - ΔG°f(reactants) = -65.3 kJ·mol⁻¹
2. Calculate K
T = (25.0 + 273.15) K = 298.15 K
