Question

I, and I, of an element are 700 and 1200K/mole respectively in 1000KJ/mole energy is supplied to the gaseous atomi
clament and the ionisation occur in succession the ratio of monovalent and divalent cations are in
A)
Di 11

Answer 1

Answer:

3:1

Explanation:

I1=700KJ/mole

I2=1200KJ/mole

Given that, Total energy = 1000KJ/mole

If I1 is 700KJ/mole, the remaining energy is 1000 – 700 = 300KJ/mole

i.e.,  1200KJ/mole→100%  I2

300KJ/mole→   ?

   = 300×1001200=25%   I2

∴  I1 = 75 % and I2 = 25%

ratio is 75 % : 25 % = 3 : 1
