What is the ratio of kinetic energies of 3 g of hydrogen and 4 g of oxygen at a certain temperature?

Options

  1. A3: 4
  2. B6: 1
  3. C12: 1
  4. D1: 12

Correct answer

C. 12: 1

Step-by-step solution

At same temperature, aligned & KE ₁ KE ₂ = n _ H n _ O ₂ & _ H = 3 2 =1.5 moles & _ O ₂ = 4 32 =0.125 moles & KE ₁ KE ₂ = 1.5 0.125 = 12 1 12: 1 aligned
