Answer:
127.013 C
Explanation:
-We apply Faraday's First Law of Electrolysis which states that the mass,m of a substance deposited is directly proportional to the current,Q passed through it:
Where Z is the proportionality constant(g/C)
-The current can therefore be calculated as:
Hence, the amount of current through the circuit is 127.013 C
Answer:
0.015 M
Explanation:
For a first order reaction;
ln[A] =ln[A]o - kt
[A] = final concentration
[A]o =initial concentration
k= rate constant
t= time taken
ln[A] =ln[A]o - kt
ln[A] = ln(0.0500) - 6.7 x 10-4 (30 × 60)
ln[A] = -2.9957 - 1.206
ln[A] = -4.202
e^ln[A] = e^(-4.202)
A= 0.015 M
Answer:
Option C = They must have same average kinetic energy.
Explanation:
According to the kinetic molecular theory,
1. The kinetic energy of gas molecules is only depend upon the temperature.
2. The gas molecules are randomly moves in any direction and thus colloid with each other and wall of container. This collision is elastic.
3. The volume of gas particles is negligible as compared to the volume of container.
4. The ideal gas does not exhibit attractive and repulsive forces.
The first postulate of kinetic molecular theory state that the average kinetic energy is depend upon the temperature so at the same temperature and pressure the two different gases have same kinetic energy.
