Answer: 0.923 L
Explanation: The reaction between naoh and h3po4 is:
3naoh + h3po4 —> na3po4 + 3h20
this means it requires 3 mols of naoh to make na3po4
given the concentration, 3.25 M, the equation looks like this:
3.0 mol x (1.0L/ 3.25mol) = 0.923 L
The order with respect to A is 2
The order with respect to B is 0.
The overall reaction order is 2.
<u>Explanation:</u>
The rate of chemical equation is represented by its rate equation. Here the rate equation of the given chemical reaction is
Here k represents the rate constant .
Order of the reaction with respect to its individual reactants is represented by the power of the the reactants in the rate equation.
Here the power of the reactant A is 0 and the power of reactant B is 2.
Hence the order with respect to A is 0 and order with respect to B is 2.
The overall order of the reaction is given by the sum of the powers of the reactants in the rate equation.
Hence the total order=2+0=2
