Which of the following statements are correct about equilibrium constant for a gaseous phuse reaction.

Options

A. Equilibrium constant cxpressed in terms of partial pressures has the unit of `("concentration")^(Delta n)`
B. Equilibrium constant expressed in terms of concentrations has the unit of `("concentration")^(Delta n)`
C. quilibrium constant expressed in terms of relative activity (i.e. the activity of substance relative to its activity in standard state has no unit.
D. Equilibrium constant is written simply as` k^(@)` in terms of relative activity = `k_(p) xx p^(@) ` where `p^(@)` = 100 k pa in standard state for gases

Answer

A, B, C, D
