Consider the reaction: CO2(g) + CCl4(g) ⇌ 2 COCl2(g)

ΔG° = 46.9 kJ

Under the following conditions at 25°C:

PCO2= 0.459 atm, PCCl4= 0.984 atm, and PCOCl2= 0.653 atm, ΔG for the reaction is , and the forward the reaction is

Which statement about hf is true? it is zero for any compound in its standard state. it is positive when the bonds of the product store more energy than those of the reactants. it is negative when a compound forms from elements in their standard states. it is zero for any element that is in the liquid state.
