Indicate whether the statement is true or false

Question 2

Find E for the reaction below if the process is carried out at a constant pressure of 1.00 atm and V (the volume change) = -24.5 L. (1 L atm = 101 J) 2 CO(g) + O2 (g) 2 CO2(g) H = -566. kJ

A) +2.47 kJ
B) -2.47 kJ
C) -564 kJ
D) -568 kJ

Question 3

Why are chlorofluorocarbons so damaging to the ozone layer when they are such stable molecules?

A) They contain a double bond that ozone readily attacks, resulting in the destruction of the ozone.
B) They are very light molecules that rapidly diffuse into the upper atmosphere and block the radiation that causes formation of ozone.
C) They are greenhouse gases that raise the temperature above the dissociation temperature of ozone.
D) The radiation in the stratosphere dissociates them producing chlorine atoms that catalytically destroy ozone.
E) CFCs do not damage the ozone.
