For the reaction H₂(g) + I₂(g)------2HI(g)

The equilibrium constant K_p depends on the

(a)Total pressure (b)Catalyst used.

(c)Amount of H₂ and I₂. (d) Temperature.

dream

i suppose the answer is
c)

since the no of moles of reactant = no of moles of product, K is independent of total pressure
also the value of K for any reaction is independent of catalyst as it affects both forward and backward reaction to same extent
om writing the expression for K for the reaction , it comes out to be dependent on initial no of moles of H2 and I2

The answer is d. Please explain

deedee

yup itz d

it dont depend on pressure as no of moles of rweacnts n product r same

bt it depends on temp

if d reaction si xothremic n d temp is decresesd then d reaction shifhts in 4wrd dircrtion

if d reaction is endothermic n temp s incresed tehn d reaction shfts in forwrd direction

note that all eqbm constants are dependent on temperature
