Unit 10 Test Review

1. Dinitrogen trioxide gas decomposes to nitrogen monoxide gas and nitrogen dioxide gas in an endothermic process. Predict the effect of the following changes on the position of the equilibrium; that is, state which way the equilibrium will shift (left, right, or no change) when each of the following changes is made. Explain how Keq will be affected. a) Add more dinitrogen trioxide b) add more nitrogen dioxide c) increase the volume of the reaction flask d) lower the temperature
