Question

Under chemical equilibrium, the concentration of the reaction is equal to the concentration of the products. Under chemical equilibrium, the rate of the forward reaction is equal to the rate of the reverse reaction. In the Chatelier's Principle, the term "stress" refers to the death of a loved one, too much workload, and the deprivation of food and steep. In lessthanorequalto Chatelier's Principle, the term "stress" refers to changing the temperature of the reaction, changing the pressure, and/or changing the concentration of the reactants and products. The reaction 2 SO_2(g) + O_2(g) rightarrow 2 SO_3(g) + heat is an exothermic reaction How will each of the following changes affect the equilibrium concentrations of each gas once equilibrium is re-established, i.e., will the reaction shift right or left? adding more O_2 to the container adding more SO_3 to the container condensing and removing SO_3 placing the container in a hot plate cooling the container

Explanation / Answer

2so2 +o2       --2so2 +heat

How with each of the following changes affect the equilibrium concentration of each gas once equilibrium is re established

============================================================

Adding more o2 to the container

Adding oxygen causes the reaction to SHIFT RIGHT in order to use it up. This results in more so3 being formed Ke of will not change

======================================================

Adding more so3 to the container

Adding more so3 to the container causes the reaction to SHIFT LEFT .

Rate of reaction decreases as product formed and exothermic

======================================================

Condensing and removing SO3

removing SO3 removing SO3 the reaction to SHIFT RIGHT

=====================================================

Placing the container in a hot plate

Raising the temperature of an exothermic causes the reaction to shift to LEFT , using up the added heat. So3 is reduced

Keq DECREASE due to relative greater increase in the rate of the endothermic reaction

=====================================================

Colling the container   -shift right

As reaction is endothermic and condensation .........……leads to formation so3
