At –17.9 °C the concentration equilibrium constant K =7.8 × 10 for a certain reaction. Here are some facts about the reaction: • Some of the reactants are liquids and solids. • If the reaction is run at constant pressure, the volume increases by 9.7%. • If the reaction is run at constant pressure, 70.0 kJ/mol of heat are released. O Yes. Oxto Using these facts, can you calculate K, at -28. °C? O No. If you said yes, then enter your answer at right. Round it to 2 significant digits. Yes, and K will be bigger. If you said no, can you at least decide whether K at Yes, and K will be -28. °C will be bigger or smaller than K at – 17.9 °C? smaller.

Question
At -17.9 °C the concentration equilibrium constant K. =7.8 × 10 - 5 for a certain reaction. Here are some facts about the reaction: • Some of the reactants are liquids and solids. • If the reaction is run at constant pressure, the volume increases by 9.7%. • If the reaction is run at constant pressure, 70.0 kJ/mol of heat are released. Yes. x10 Using these facts, can you calculate K, at -28. °C? C. O No. If you said yes, then enter your answer at right. Round it to 2 significant digits. Yes, and K, will be bigger. If you said no, can you at least decide whether K, at Yes, and K will be -28. °C will be bigger or smaller than K. at – 17.9 °C? smaller.
