do not write outside the box the following dynamic equilibrium was established at temperature t in a closed container p g q g r g h kj mol the value of kc for the reaction was mol dm when the equilibrium mixture contained mol of p and mol of r a give the meaning of the term dynamic equilibrium marks extra space b write an expression for kc for this reaction mark c the volume of the container was dm calculate the concentration in mol dm of q in the equilibrium mixture marks extra space wmp jun chem do not write outside the box d state the effect if any on the equilibrium amount of p of increasing the temperature all other factors are unchanged mark e state the effect if any on the equilibrium amount of p of using a container of larger volume all other factors are unchanged mark f state the effect if any on the value of kc of increasing the temperature all other factors are unchanged mark g state the effect if any on the value of kc of using a container of larger volume all other factors are unchanged mark h deduce the value of the equilibrium constant at temperature t for the reaction r g p g q g mark turn over for the next question turn over wmp jun chem
