For a reversible gaseous reaction
N2 + 3H2 ⇌ 2NH3 at equilibrium, if some moles of H2 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 some time will be radioactive.
(b) moles of N2 after the change will be different as compared to moles of N2 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
Correct answer: (a) the sample of ammonia obtained after some time will be radioactive.
Explanation:
Since T2 has similar chemical properties as H2 so upon mixing, NH2T and NHT2 are formed.
