<u>Answer:</u> The standard Gibbs free energy of the given reaction is 6.84 kJ
<u>Explanation:</u>
For the given chemical equation:
The expression of for above equation follows:
We are given:
Putting values in above expression, we get:
To calculate the equilibrium constant (at 25°C) for given value of Gibbs free energy, we use the relation:
where,
= standard Gibbs free energy = ?
R = Gas constant = 8.314 J/K mol
T = temperature =
= equilibrium constant at 25°C = 0.0632
Putting values in above equation, we get:
Hence, the standard Gibbs free energy of the given reaction is 6.84 kJ

Answer:
Synergism
Explanation:
Synergism -
It refers to the process of interaction between the any two or more chemicals , i.e. , combining the chemicals increases the effect of the chemical , is referred to as synergism .
The individual drug or chemical might not be strong or harmful in any respect , but combining it with various other drugs or chemical , might make it very strong or harmful .
Hence ,from the given scenario of the question ,
The correct answer is synergism .
Answer:
Montreal protocol is an international treaty signed by many countries across the globe to regulate the manufacturing and usage of substances like chlorofluorocarbons and to take measures to protect the ozone layer.
Explanation:
Montreal protocol was signed on 16th September 1987 and it was enforced on January 1st 1989. It was singed all the 197 countries who acknowledged the importance of restoring and protecting the ozone layer. The treaty has various articles under it like -(Article 2) Calculation of control levels to control the usage of ozone depleting substances.
some of the recent measures to reduce CFCs are:-
1. UN environment programme had released a list of products for the public that deplete the ozone layer and another list that doesn't. so that the public can make wise purchasing decisions.
2. Safe disposal of appliances like ACs, refrigerator and coolers that contain CFCs
3. Different policies are made by the UN environmental protection agency and organisations like national resource defense council to regulate and reduce the production and usage of CFCs.
