Answer:
for the reaction is 18.05
Explanation:
Equilibrium constant in terms of partial pressure (
) for this reaction can be written as-

where
and
are equilibrium partial pressure of
and
respectively
Hence
= 18.05
So,
for the reaction is 18.05
Answer: B= Rusting ability
Explanation:
Physical property is defined as the property which can be measured and whose value describes the state of physical system. For Example: State, density etc.
Chemical property is defined as the property of a substance which is observed during a reaction where the chemical composition identity of the substance gets changed.
1. Boiling point: is a physical property as there is a change of state.
2. Rusting ability: is a chemical property as there is formation of new substances.
3. Melting point: is a physical property as there is a change of state.
4. Density: is a physical property as there is no formation of new substances.
