Answer:
Joule-Thomson coefficient for an ideal gas:
Explanation:
Joule-Thomson coefficient can be defined as change of temperature with respect to pressure at constant enthalpy.
Thus,
Also,
Also, is defined as:
Acoording to defination, the ethalpy is constant which means
For an ideal gas,
So,
Thus, ≠0. So,
Answer:
Mechanical energy is basically the energy of movement
For example, if I am running, im using Mechanical energy
Answer:
The decomposition of ethane is 153.344 times much faster at 625°C than at 525°C.
Explanation:
According to the Arrhenius equation,
where,
= rate of reaction at
= rate of reaction at
= activation energy of the reaction
R = gas constant = 8.314 J/K mol
The decomposition of ethane is 153.344 times much faster at 625°C than at 525°C.

Answer:
Explanation:
Octet, in chemistry, the eight-electron arrangement in the outer electron shell of the noble-gas atoms. This structure is held responsible for the relative inertness of the noble gases and the chemical behaviour of certain other elements.
