The equilibrium reaction between copper (l) chloride and chlorine at 25oC and 1 atmosphere is represented by the equation:
2CuCl +Cl2 ⇌ 2 CuCl2 ∆H = – 166 KJ. Which of the following statements is TRUE for the reaction, pressure remaining constant?

  • more CuCl is formed at 40oC
  • more CuCl2 is formed at 10oC checkmark
  • Less CuCl2 is formed at 10oC
  • there is no change in the amount of CuCl2 formed at 40oC and10oC
  • more CuCl is consumed at 40oC

The correct answer is: B
