The rate of reaction is 0.050 mol·s⁻¹.
For the reaction
[tex]P_4 + 5O_2 \longrightarrow P_4O_{10}\\[/tex]
[tex]\text{rate} = \frac{\Delta P_4O_{10} }{\Delta t } = \frac{\text{1.5 mol }}{\text{ 30 s }} = \text{0.050 mol}\cdot \text{s}^{-1}\\[/tex]
Answer
Vr = 0.5mol / s
Explanation
To calculate the reaction rate we have to divide the amount of substance consumed and the time it was consumed.
Vr = mol / t = 1.5moles / 3s
Vr = 0.5mol / s
