If 38 55 ~kJ of heat is absorbed when 6 0 ~g of O ₂ react with CIF according to reaction 2 CIF _ ( g ) + O _ 2( ~g ) Cl ₂ O _ ( g ) +0 ~F ₂( ~g ) What is the standard enthalpy of reaction?

Options

  1. A72.28 ~K
  2. B205.6 k J
  3. C102.8 k ]
  4. D49.80 k ]

Correct answer

B. 205.6 k J

Step-by-step solution

(A) array l 2 ClF _ ( g ) + O _ 2( ~g ) Cl ₂ O _ ( g ) + OF _ 2( ~g ) For 6.0 ~g of O ₂ H =+38.55 ~kJ For 32.0 ~g of O ₂ H ⁰= 38.55 32 6 =205.6 ~kJ array
