A chemist was able to measure the value of lattice energy of KCI to be 690 kJ/ mol. From this experiment he concluded that

  • (A) lattice energy of KBr is 630 kJ/mol and that of KI is 665 kJ/mol
  • (B) lattice energy of KBr is 665 kJ/mol and that of KI is 630 kJ/mol
  • (C) lattice energy of KBr is 765 kJ/mol and that of KI is 730 kJ/mol
  • (D) lattice energy of KBr is 730 kJ/mol and that of KI is 765 kJ/mol;
