When a chemical reaction is at equilibrium, the forward and reverse reactions occur at the same rate. The concentrations of the different compounds in the reactions will remain constant. The relationship between the concentrations of the reactants and products is expressed as the equilibrium constant, K.. Part A Balance this equation, and then enter the coefficients, in order, below. CCl,(g) + O2(g) = COCl (g) - Cl (8) Express your answer as integers separated by commas (e.g. 1, 2, 3,...

When ΔG ̊=0, the system is at equilibrium and both the forward
and reverse reaction are proceeding at equal rates. This is the
case during phase transitions. Consider the phase transition and
the data shown for BCl3 below. Calculate the boiling point (in ̊C)
for BCl3. BCl3(l) ⇄ BCl3(g) Hf ̊ (kJ/mole) S ̊ (J/mol∙K) BCl3(l)

Select all of the correct statements about equilibrium from the choices below. At equilibrium the rates of forward and reverse reactions are equal. At equilibrium all reactions stop. At equilibrium the rate of change of product concentration is zero. At equilibrium the speed of a reaction equals its rate constant. As a reaction proceeds forward toward equilibrium the forward rate constant drops. At equilibrium the forward rate constant equals zero.
