Question

During this reaction : P 4 + 5O 2 P 4 O 10 , 1.5 moles of product was made in 30 seconds. What is the rate of reaction?

Answer 1

The rate of reaction is 0.050 mol·s⁻¹.

For the reaction

`P_4 + 5O_2 \longrightarrow P_4O_(10)\\`

`\text{rate} = (\Delta P_4O_(10) )/(\Delta t ) = \frac{\text{1.5 mol }}{\text{ 30 s }} = \text{0.050 mol}\cdot \text{s}^(-1)\\`

Answer 2

Vr = 0.5mol / s

Step-by-step 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
