1. The problem statement, all variables and given/known data At a certain temperature, the reaction 2NO2(g) --> 2NO(g) + O2(g) progresses in a 4.00 liter vessel at a rate of 0.88 mol · L−1· s−1. What is [tex]\Delta[/tex][NO2] [tex]\Delta[/tex]t under these conditions? Answer in units of mol · L−1· s−1. 2. Relevant equations C = n/v ...? 3. The attempt at a solution I'm not at all sure where to start with this one. My only work with mol/Ls was finding the rate that a product was made compared to the reactant. Could I get a starting point?
