ANSWER:Step 1 of 6
The reaction is shown below.
Le Chatelier's principle suggests that any change in the parameters like temperature, pressure, volume of any equilibrium reaction is affecting the equilibrium condition of the reaction. This change in equilibrium is adjusted by the reaction by changing the equilibrium towards the left or right hand side of the reaction.
