- Can you please help us with number 10 in the picture. we get 1.4 = log A/HA. so we figure this means because it is greater than one, the reaction shifts to the left and therefore A - > H. We are not sure.This is not a graded question as it is a practice question . I am 60 years old and helping my son prepare for the AP exam in a few months.

- Prof. Neiman and Prof. James were first to discovered in 1973 that chlorofluorocarbons (CFCs) were depleting the Earth’sozone layer when released into the atmosphere. Once they reach the stratosphere, Clis released from the CFCs molecules by interaction with UV light. Free Cl atoms areable to react with ozone in a catalytic cycle that converts O3into the more stable O2.It is estimated that a single Cl atom is able to react with∼100000 O3molecules.Although CFCs production was banned in 1996, there are still a substantial numberof motor vehicle air conditioners (MVACs) that use CFC-12 (CF2Cl2) as refrigerant.The average CFC-12 emission rate from operating MVACs has been estimated tobe 59.5 mg per hour per vehicle (Zhang et al.Environ. Sci. Technol. Lett.2017).How much chlorine, in kg, is added to the atmosphere in a year due to 100 millionMVACs using CFC-12 as refrigerant?32 Consider the following potential energy diagram (Image 1) for the general reaction: Reactants ?
