Phosgene decomposes according to the following reaction COCl2(g) ⇌ CO(g) + Cl2(g) Kc = 0.963 at 27.0 oC If the initial concentration of each substance is 0.546 M, what is the final concentration of Cl2?

Acalorimeter is to be calibrated: 51.203 g of water at 55.2 degree c is added to a calorimeter containing 49.783 g of water at 23.5c. after stirring and waiting for the system to equilibrate, the final temperature reached is 37.6 degree c. specific heat capacity of water (s = 4.18 j/g∙degree c). calculate the calorimeter constant. (smδt)warm water = -[(smδt)cold water + (calorimeterδtcold water)]
