Answer
- increase in temperature
- decrease in pressure
- continuous removal of PH3
- adding more of P into the system
Explanation:
In the reaction P4(g)+6H2(g) ⇌ 4PH3(g);
- The effect of temperature on equilibrium has to do with the heat of reaction. Recall that for an endothermic reaction, heat is absorbed in the reaction, and the value of ΔH is positive. Thus, for an endothermic reaction, we can picture heat as being a reactant:
heat+A⇌BΔH=+
- Since the reaction is endothermic reaction, heat is a absorbed. Decreasing the temperature will shift the equilibrium to the left, while increasing the temperature will shift the equilibrium to the right forming more of PH3.
- According to Le Chatelier’s principle, adding additional reactant to a system will shift the equilibrium to the right, towards the side of the products. In the same Way, reducing the concentration of the product will also shift equilibrium to the right continually forming PH3 as it is removed.
The product formation at equilibrium has been increased with an increase in temperature, decrease in pressure, increase in reactants, and decrease in products.
The reaction of formation of [tex]\rm PH_3[/tex] has the value of [tex]\rm \Delta H[/tex] to be positive. This indicates the reaction has absorbed energy formation of the product.
The product formed has high energy, thus an increase in the energy provided to the system has been responsible for the increase in the product.
The product concentration has been increased from the equilibrium by:
- Increase in temperature: It has been an endothermic reaction, thus more energy results in more quantity of the product formation at equilibrium.
- Decrease in pressure: It has been stated that with a decrease in pressure, the equilibrium has been shifted to the right with increased product formation.
- Increase in reactant concentration: The increase in the reactants results in more formation of the product..
- Decreased concentration of product: With the decrease in the product concentration with continuous removal of the product, there has been a dis balance in the equilibrium, and the product formation has been increased.
The product formation at equilibrium has been increased with an increase in temperature, decrease in pressure, increase in reactants, and decrease in products.
