<u>Answer:</u> The volume of HCl needed is 0.250 L
<u>Explanation:</u>
To calculate the number of moles for given molarity, we use the equation:
<u>For sodium carbonate:</u>
Molarity of sodium carbonate solution = 0.500 M
Volume of solution = 0.750 L
Putting values in above equation, we get:
The chemical equation for the reaction of sodium carbonate and HCl follows:
By Stoichiometry of the reaction:
1 mole of sodium carbonate reacts with 2 moles of HCl
So, 0.375 moles of sodium carbonate will react with = of HCl
Now, calculating the volume of HCl by using equation 1:
Moles of HCl = 0.750 moles
Molarity of HCl = 3.00 M
Putting values in equation 1, we get:
Hence, the volume of HCl needed is 0.250 L

(3)
(4)
Explanation :
Rate law : It is defined as the expression which expresses the rate of the reaction in terms of molar concentration of the reactants with each term raised to the power their stoichiometric coefficient of that reactant in the balanced chemical equation.
The general reaction is:
