Answer:
Explanation:
We know,
where, R = 0.0821 L.atm/(mol.K), T is temperature in kelvin and is difference in sum of stoichiometric coefficient of products and reactants
Here and T = 311 K
So,
Hence value of equilibrium constant in terms of partial pressure is
Answer : The correct option is, (C) 2, 4 and 5.
Explanation :
Combustion reaction : It is a type of reaction in which a hydrocarbon react with an oxygen molecule to give carbon dioxide, water as a product.
For example : Methane react with oxygen to give carbon dioxide and water.
In the given list of chemical substances, are in oxide form. They can not be both reactant and product of a single combustion reaction.
In the given list, is the only hydrocarbon which shows a combustion reaction. That means
react with
to give
and
as a product.
The balanced combustion reaction of is,
Therefore, the correct answer is, (C) 2, 4, and 5.
