Answer:
Spontaneous and random. Decay is called spontaneous because the occur on their own and are unaffected by external factors like temperature, pressure, and many more. Decay is called random because we cannot determine the rate at which it decays but can only determine the probability of the decay.Oct 21, 2015
Explanation:
Cl2 means two Cl or chlorine atoms bonded two each other. 2Cl means t who separate chairing atoms.
The answer for the following problem is mentioned below.
Therefore the Gibbs free energy (ΔG) for the reaction is <u><em>-394.36 J</em></u>
Explanation:
Given:
ΔH = -393.5 kJ/ mol
ΔS =0.0029 kJ/mol K
T = 298 K
To solve:
Gibbs free energy (ΔG)
We know;
<u>ΔG = ΔH - TΔS </u>
ΔG = -393.5 - (298 × 0.0029)
ΔG = -393.5 - 0.8642
<u><em>ΔG = -394.36 J</em></u>
Therefore the Gibbs free energy (ΔG) for the reaction is <u><em>-394.36 J</em></u>
<u><em></em></u>
Answer: Option (B) is the correct answer.
Explanation:
When the book was at the shelf, it had only potential energy as potential energy is the energy possessed due to the position of an object.
Therefore, when the book falls from the book shelf it gains kinetic energy as kinetic energy is the energy possessed due to the motion of an object.
Thus, when the books is falling from the top shelf then the motion of book increases therefore, we can conclude that the potential energy decreases as kinetic energy increases.
