Calculate the magnitude of the cohesive energy of potassium

Reference no: EM13705128

Problem- 1) What is the magnitude of the energy of a bond formed between a potassium (K+) cation and an iodide (I?) anion? The ionic radii of K+ and I?, are 152 pm and 206 pm, respectively. Assume the Born exponent n is 10. Please report your answer in joules.

2) Calculate the magnitude of the cohesive energy of potassium iodide (KI). The ionic radii of K+ and I?, are 152pm and 206 pm, respectively. Assume the Born exponent n is 10. Assume a Madelung constant of 1.7. Please report your answer in kJ/mol?
