Consider the following reaction:
2HBr(g)---> H_2(g) + Br_2(g)
B)In the first 15.0s of this reaction, the concentration of HBr dropped from 0.510M to 0.455M. Calculate the average rate of the reaction in this time interval.
C)If the volume of the reaction vessel in part (b) was 0.500L, what amount of Br_2 (in moles) was formed during the first 15.0s of the reaction?
I got the answer for part B and it was 1.8*10^-3.
