Answer:
7.8 × 10∧-4 nm³
Explanation:
Given data:
volume = 7.8x10^-31 m^3
volume in nm³= ?
Solution:
I m³ = 1 × 10∧27
7.8 x 10^-31 × 1 × 10∧27 = 7.8 × 10∧-4 nm³

Answer : The value of
is -24.9 kJ/mol
Explanation :
First we have to calculate the value of 'Q'.
The given balanced chemical reaction is,

The expression for reaction quotient will be :

In this expression, only gaseous or aqueous states are includes and pure liquid or solid states are omitted.
Now put all the given values in this expression, we get


Now we have to calculate the value of
.
The formula used for
is:
............(1)
where,
= Gibbs free energy for the reaction = ?
= standard Gibbs free energy = -28.0 kJ/mol
R = gas constant = 
T = temperature = 298 K
Q = reaction quotient = 3.375
Now put all the given values in the above formula 1, we get:


Therefore, the value of
is -24.9 kJ/mol
