1. calculate the average reaction rate expressed in moles h2 consumed per liter per second.
2. calculate the average reaction rate expressed in moles ci2 consumed per liter per second.

1) 0.0025 mol/L.s.

2) 0.0025 mol/L.s.

Explanation:

H₂ + Cl₂ → 2HCl.

The average reaction rate = - Δ[H₂]/Δt = - Δ[Cl₂]/Δt = 1/2 Δ[HCl]/Δt

1. Calculate the average reaction rate expressed in moles H₂ consumed per liter per second.

The average reaction rate expressed in moles H₂ consumed per liter per second = - Δ[H₂]/Δt = - (0.02 M - 0.03 M)/(4.0 s) = 0.0025 mol/L.s.

2. Calculate the average reaction rate expressed in moles CI₂ consumed per liter per second.

The average reaction rate expressed in moles Cl₂ consumed per liter per second = - Δ[Cl₂]/Δt = - (0.04 M - 0.05 M)/(4.0 s) = 0.0025 mol/L.s.

the atomic mass is the bottom number on the element.
