Question

At any temperature for the following reaction, (D T are deuterium and tritium respectively) correct statement is (i) HCl + F → HF + Cl (ii) DCl + F → DF + Cl (iii) TCl + F → TF + Cl (A) (i) is fastest (B) (ii) is fastest (C) (iii) is fastest (D) All the above reactions occur at same rate

Tardigrade Admin · Accepted Answer

Lighter isotopes possess low bond dissociation energy and hence react faster relatively

Q. At any temperature for the following reaction, (D & T are deuterium and tritium respectively) correct statement is (i) HCl+F→HF+Cl (ii) DCl+F→DF+Cl (iii) TCl+F→TF+Cl

(i) is fastest

(ii) is fastest

(iii) is fastest

All the above reactions occur at same rate

Lighter isotopes possess low bond dissociation energy and hence react faster relatively
