Answer: 850.0 g/min.

Explanation:

The rate of the reaction = (ΔC/Δt) where,

ΔC is the change in concentration of reactants or products.

Δt is the change in time of the reaction proceeding.

The rate is needed to be calculated in (g/min). We need to calculate the amount of the product in (g) via using the relation (n = mass / molar mass). mass (g) = n x molar mass, n = 1.5 moles and molar mass of P₄O₁₀ = 283.88 g/mol. m = 1.5 x 283.88 = 425.82 g. ΔC = 425.82 g and Δt = 30 s / 60 = 0.5 min. The rate of the reaction = ΔC / Δt = (425.82 g / 0.5 min) = 851.64 g/min.

can be approximated to 850.0 g/min.
