The relationship between ( K _ p ) and ( K _ c ) is ( K _ p = K _ c ) (RT) ( ^ n_ g ). What would be the value of ( n_ g ) for the reaction ( NH ₄ Cl ( s ) NH ₃( ~g )+ HCl ( g ) ? )
Options
- A( 11 )
- B( 0.5 )
- C( 1.5 )
- D( 12 )
Correct answer
D. ( 12 )
Step-by-step solution
We know K _ p = K _ c ( RT )^ n_ g n_ g = no. of moles of products in gaseous phase - no. of moles of reactants in gaseous phase. For the given reaction N H₄ C l(S) N H₃(g)+H C l(g) n_ g =2-0=2 Therefore, K_ p =K_ c (R T)⁰ or K_ p =K_ c
