Question

nitrogen and hydrogen in the molar ratio 1:3 was allowed to equilibrate. if 50% of each reacts with total pressure of P, then kp for the reaction
n2+3h2 ---->2nh3 is

Answer 1

Explanation:

There is a mixture of nitrogen and hydrogen in the ratio of 1:3 that reach the equilibrium when 50℅ of the mixture has reacted. If the total pressure is P, then find the partial pressure of ammonia in the equilibrium mixture is what?

N2+3H2=======>2NH3.

At the start of the reaction the Pressure was'P'.

Suppose if we consider 1 mole of N2 gas and 3 moles of H2 gas was present in the beginning.(4 moles)

After the completion of 50% of the Reaction, 0.5 mole of N2, 1.5 mole of H2 and 1 mole of NH3 will be present.

So the initial 4 moles will be now (0.5+1.5+1)=3 moles will be present at the equilibrium after the completion of 50% reaction. So the Pressure at equilibrium will be 3/4 x P. = 0.75 P.

The partial pressure of Ammonia = 0.75 x (1/3) x P

= 0.25P
