Answer: Option (e) is the correct answer.
Explanation:
An equilibrium reaction is defined as the reaction where rate of forward reaction will be equal to the rate of backward reaction.
For example, 
So, here amount of reactants that is, nitrogen gas and hydrogen gas will be constant along with constant amount of formation of product that is, ammonia here.
In an equilibrium reaction there is presence of both reactants and products and hence, both reactants and products constitute the system.
Thus, we can conclude that all the given statements are true.
Answer:
The amount of kinetic energy an object has depends on its
Motion
Explanation:
Only kinetic energy increases when the velocity of an object increases.
Answer: Option (a) is the correct answer.
Explanation:
According to thermodynamics, a closed system is defined as the system in which there will be no exchange of matter takes place but there will be exchange of energy between the system and surrounding.
On the other hand, an open system is defined as the system in which there will be exchange of both matter and energy takes place between system and surrounding.
Hence, we can conclude that out of the given options accurate descriptions of closed and open thermodynamic processes is that open processes are 'flow through' processes.
