Which of these scenrios involve a reaction that is equilibrium?
a. the reaction is producing reactants and produces at an equal rate
b. the reaction is producing more reactants than products
c. the reaction is producing more products than reactants
d. the reaction is only producing products

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)]
