Assertion: Recent convention to represent K_(p) is dimensionless. Reason: The statement state of pure gas is 1 bar and the partial pressure of reactants and products measured with respect to this standerd are determine K_(p) for the equilibrium. A(g) + 2B(g) rarr C(g)

Answer»

If both assertion and REASON are true and the reason is the correct explanation of the assertion.
If both assertion and reason are true but reason is not the correct explanation of the assertion.
If assertion is true but reason is false.
If assertion is false but reason is true.

Solution :LET partial pressure of reactants and products are a,b,c BAR respectively with respect to STANDARD state, then
For `A(g) + 2B(g)` `rarr` `C(g)`
`P'_(A) = (alpha bar)/(1 bar) = 1`
Similarly, `P'_(B) = b` and `P'_(c) =0`
Thus, `K_(p) = (c)/(axxb^(2))` is dimensionless.
