For a reversible gaseous reaction `N_(2) + 3H_(2) harr2NH_(3)` at equilibrium, if some moles of `H_(2)` are replaced by same number of moles of `T_(2)` (T is tritium, isotope of H and assume isotopes do not have different chemical properties) without affecting other parameters, then:

Options

A. The sample of ammonia obtained after sometime will be radioactive
B. Moles of `N_(2)` after the change will be different as compared to moles of `N_(2)` present before the change
C. The value of `K_(p) or K_(c)` will change
D. The average molecular mass of new equilibrium will be same as that of old equilibrium

Answer

A
