Question

For a reversible gaseous reaction N2 +3H2 → 2NH3 at equilibrium, if some moles of H, are replaced by same number of moles of T2 (T is tritium, isotope of H and assume isotopes do not have different chemical properties) without affecting other parameters, then:

(a) the sample of ammonia obtained after sometime will be radioactive.

(b) moles of N2 after the change will be different as compared to moles of N present before the change

(c) the value of Kp, or Kc will change

(d) the average molecular mass of new equilibrium will be same as that of old equilibrium

Answer 1

I think it is A - the sample of ammonia obtained after sometime will be radioactive,

Because Tritium is a radioactive isotope of the element hydrogen.

Answer 2

Answer:

a) the sample of ammonia obtained will be radioactive

Explanation:

Instead of NH3, either $NH_{2} T$ or $NHT_{2}$ is obtained.

Why?

Since Tritium is a radioactive isotope of hydrogen.
