Outline the steps needed to determine the limiting reactant when 0.50 mol of Cr and 0.75 mol of H3PO4 react according to the following chemical reaction. 2Cr + 2H3PO4 -> 2CrPO4 + 3H2

Sagot :

The theoretical yield of the reaction is 1.13 g. The acid H₃PO₄ is the limiting reactant.

Definition of the theoretical yield

The theoretical yield of a given chemical reaction can be obtained from the balanced reaction equation.

Number of moles of Cr =  0.50 g /52 g/mol = 9.6 × 10⁻³ moles

Number of moles of acid =  0.75 g/98 g/mol = 7.7 × 10⁻³ moles

Given that the reaction is 1:1, the limiting reactant would be the acid.

The theoretical yield that is obtained from,

Theoretical yield = Number of moles of product × Molar mass of product

Substitute the values to obtain,

7.7 × 10⁻³ moles × 147 g/mole = 1.13 g
