The reaction rate increases. The reaction is exothermic. This information is useless. The reaction is endothermic.

For the following reaction, N204(g) → 2NO2(g), the value of Ke is 1.2x10-5 at a certain temperature. If the reaction mixture is found to contain 0.0020 M NO2 and 0.0075 M N204, what is the value of Q and what does this mean? Periodic Table and Datasheet Q K and the reaction will proceed towards the reactants. Q > K and the reaction will proceed towards the products.
