The formation of ammonia is an equilibrium reaction; N2(g) + 3 H2(g) <--> 2 NH3(g) the enthalpy of this reaction is negative. What can be done to increase the yield of products?

Using le Chatelier's principle that when a change occurs in a system at equilibrium the system will counteract the change to establish a new equilibrium we can answer this question. If the pressure is inc...

Magnesium reacts with hydrochloric acid to form a salt. What volume of 0.2dm(-3) HCL is required to react with 4g of Magnesium? Give answer in cm(3).

First draw out the equation. Mg + HCL = MgCl2 + H2Now balance this equation Mg + 2HCl = MgCl2 + H2Next we need to work out the moles of Mg. We know that we have...

Explain Le Chatelier's Principle

In a chemical equilibrium, the position of the equilibrium will always move to oppose any change in temperature, pressure or concentration of reactants/products. For example, if temperature is increased, ...

How does temperature affect the position of equilibrium if the reaction is exothermic?

Imagine the reaction A + B <-> C+D where the forward reaction is exothermic. If we increase the temperature of the surroundings, the equilibrium is going to shift to the direction that reduces the t...
