Question
Determine the direction of the reaction, if any, for the following conditions in the reaction below:
4 HCl (g) + O2 (g) 2 H2O (g) + 2 Cl2 (g) H = 28 kcal
Condition
Direction of Reaction
Addition of oxygen gas
An increase in temperature
Reduction in the volume of the container
Addition of a catalyst
Removal of HCl (g) from the container
Condition
Direction of Reaction
Addition of oxygen gas
An increase in temperature
Reduction in the volume of the container
Addition of a catalyst
Removal of HCl (g) from the container
Explanation / Answer
4 HCl (g) + O2 (g) 2 H2O (g) + 2 Cl2 (g) H = 28 kcal
Condition
Direction of Reaction
Addition of oxygen gas
shifts to right direction
An increase in temperature
shifts to right direction
Reduction in the volume of the container
shifts to right direction
Addition of a catalyst
No shift
Removal of HCl (g) from the container
shifts to left direction
Explanaition :
if adding oxygen gas concentration of reactants increases. so the reaction shifts to right direction.
this is endothermic reaction . if increasing temperature shift the reaction right.
adding catalyst no change.
