<span>In a dissolving process,
energy is required to overcome the forces of attraction between the solvent
particles. The first step is for the solvent particles to move in order for
solute particles to enter the system. This process is endothermic where energy
flows into the system. The second step is when solute particles must separate
from other solute particles. Lastly, the solute should move between solvent
particles.</span>
<u>Answer:</u> The rate law for the given chemical equation is
<u>Explanation:</u>
Rate law is defined as the expression that expresses the rate of the reaction in terms of the molar concentration of all the reactants each term raised to the power their stoichiometric coefficient in the given balanced chemical equation.
For the given balanced chemical equation:
Rate law expression for the reaction:
Order with respect to Li = 1
Order with respect to NaCl = 1
Hence, the rate law for the given chemical equation is
Answer:
0.065M
Explanation:
The reaction expression is given as:
HCl + KOH → KCl + H₂O
Given parameters:
Volume of KOH = 25.81mL = 0.02581L
Molarity of KOH = 0.125M
Volume of HCl = 50mL = 0.05L
Unknown:
Molarity of the acid = ?
Solution:
To find the molarity of the acid, HCl, let us use the mole concept.
First, find the number of moles of the base, KOH;
Number of moles of KOH = molarity of KOH x volume of KOH
Number of moles of KOH = 0.125 x 0.0258 = 0.003225mol
From the balanced reaction equation:
1 mole of KOH reacted with 1 mole of HCl
0.003225mol of KOH will react with 0.003255mole of HCl
Molarity of HCl =
Molarity of HCl = = 0.065M
