Why does every chemical reaction require a certain amount of activation energy?
1 answer:
Explanation:
Activation energy is the minimum amount of energy required for a chemical reaction to take place.
When a chemical reaction occurs then bonds between the reactants break and bonds between the products are formed. This leads to the formation of an activated complex which is also known as transition state.
So, in order to form the activated complex a minimum amount of energy is necessary and this energy is known as activation energy.

Answer: The equilibrium concentration of hydrogen gas is 0.0269 M
Explanation:
The chemical reaction follows the equation:
At t = 0 0.044M 0.044M 0.177M
At (0.044-x)M (0.044-x)M (0.177+x)M
The expression for for the given reaction follows:
We are given:
Putting values in above equation, we get:
Hence, the equilibrium concentration of hydrogen gas is (0.044-x) M =(0.044-0.0171) M= 0.0269 M
