= At 7.42 °C the concentration equilibrium constant K 4.7 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, 83.0 kJ/mol of heat are absorbed. The net change in moles of gases is 2. Using these facts, can you calculate K at -20. °C? x10 ○ Yes. O No. If you said yes, then enter your answer at right. Round it to 2 significant digits. n If you said no, can you at least decide whether K at -20. °C will be bigger or smaller than K at -7.42 °C? Yes, and K will be bigger. Yes, and K will be smaller. No.
