For a reversible gaseous reaction `N_2 + 3H_2 iff 2NH_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 incorrect statement

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
