Answer: The reaction is not at equilibrium and will proceed to make more products to reach equilibrium.
Explanation:
Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios. It is expressed as
K is the constant of a certain reaction when it is in equilibrium, while Q is the reaction quotient of activities of products and reactants at any stage other than equilibrium of a reaction.
For the given chemical reaction:
The expression for is written as:
Given : = 54.8
Thus as , the reaction will shift towards the right i.e. towards the product side.
Answer:
0.5 moles of Pb(OH)₂ are produced.
Explanation:
The reaction is:
If we have 1.0 liter of 1.0 M of sodium hydroxide and lead (II) nitrate, the number of moles are:
Now, we need to find the limiting reactant knowing that 2 moles of sodium hydroxide react with 1 mol of lead (II) nitrate:
Since we have 1 mol of sodium hydroxide and we need 2 moles to react with lead (II) nitrate, then the limiting reactant is sodium hydroxide.
We can find the number of moles of lead (II) hydroxide produced as follows:
Therefore, 0.5 moles of Pb(OH)₂ are produced.
