Chlorine reacts with carbonmonoxide to produce phosgenegas, COCl 2. A catalyst is used. Cl 2+ COCOCl 2The reaction is exothermic. Explain why the reaction is exothermic in terms of the energy changes of bond breaking and bond making. Complete the energy level diagram for this reaction. On your diagram show: ● the product of the reaction ● an arrow representing the energy change, labelled ∆H ● an arrow representing the activation energy, labelled A. energy progress of reaction Cl 2+ CO State why a catalyst is used. Describe and explain the effect, if any, on the position of equilibrium when: the pressure is increased the temperature is increased. The reaction between chlorine and carbonmonoxide can be represented as shown. Cl Cl Cl + CO C O Cl When one mole of chlorine reacts with one mole of carbonmonoxide, 230 kJ of energy is released. Some bond energies are shown in the table. bond bond energy in kJ / mol Cl –Cl C=O C–Cl Use the information to calculate the energy of the bond between the C and the O in carbonmonoxide, CO. bond energy in carbon monoxide, CO = kJ / mol Complete the dot-and-cross diagram to show the electron arrangement in a molecule of COCl 2. Cl Cl C O Show outer electrons only. C Cl Cl O 0620_w21_qp_42 THEORY 2021 Paper 4, Variant 2 View
