# Problem: Consider the following reaction: H2(g) + Br2(g) → 2HBr. The graph below shows the concentration of Br2 as a function of time.Use the graph to calculate the instantaneous rate of the reaction at 25 s.

###### FREE Expert Solution

We’re being asked to calculate the instantaneous rate of the reaction at 25 s based on the graph given. An instantaneous reaction rate is the rate at a particular moment in the reaction and is usually determined graphically and can be calculated as:

Δ[  ] = change in concentration
Δt = change in time
