Consider the following reaction: 2HBr(g)→H2(g)+Br2(g)rate=−12Δ[HBr]Δt=Δ[H2]Δt=Δ[Br2]Δt In the first 20.0 s of thisreaction, the concentration of HBr dropped from 0.600 M to 0.460 M. Calculate the average rate of the reaction in this time interval.If the volume of the reaction vessel in the previous part was 1.50L , what amount of Br2 (in moles) was formed during the first 15.0s of the reaction
