If a system at equilibrium is subjected to a change of any one of the factors such as concentration , pressure or temperature, the system adjusts itself in such a way so as to minimise the effect of that change.
For the reaction
`N_(2)(g)+O_(2)(g)hArr2NO(g)`
If pressure id increased by reducing the volume of the container then :

Options

A. total pressure at equilibrium will remain same
B. concentration of all the component at equilibrium will change
C. concentration of all the component at equilibrium will ramin same
D. equilibrium will shift in the beckward direction
