Question

- Standard state refers to

a) 1 atm and 25°C

b) 1 atm and 100°C

c) 1 atm and gaseous reactants

d) None of these

Answer 1

Answer: The standard state refers to 1 atm and
`25^(o)C`.

Step-by-step explanation:

It is known that a chemical/substance can either be present in a solid, liquid or gaseous state.

So, when the phase of a substance like solid, liquid or gas is present at 1 atmosphere pressure and at a temperature of
`25^(o)C` then it known as standard state of substance.

Thus, we can conclude that standard state refers to 1 atm and
`25^(o)C`.
