a certain volume of oxygen gas is kept in a cylinder fitted with a movable piston if all the o2 molecules present in cylinder get converted to o3 at the same temperature and pressure
will there be any change in the system
calculate the percentage change if any change takes place justify answer with appropriate reasons

Answer:
If the volume occupied by a certain mass of gas is decreased by 60%, what would be the percentage change in pressure at the same ...
HOPE IT IS HELPFUL
Answer:
According to the kinetic theory of gases, yes of course there will be more collisions at a lower volume but pressure is a consequence of a force over the walls of the container, the mean sum of all collisions on the wall per unit of time do represent a net force and this force per unit of area is pressure.
The mean kinetic energy of the mass of gas that crashes against the walls is (KE)= (1/2)mv^2 and its derivative is the mean momentum =mv, following this route if thought we get again the derivative as a function of time of this momentum d(p)/dt = mdv/dt is mean force as dv/dt =a so (F)= ma so if this mass of gas m is that assigned to a unit of area A then the mean pressure if this mass is (P )= (F)/A.
