At which temperature would a reaction with H -92 kJ/mol, S -0.199 kJ/(mol-K) be spontaneous? A.600k B.500k C.400k D.700k
stiv31 [10]

Given information : H = -92 KJ/mol and S = -0.199 KJ/(mol.K)

At equilibrium G = 0

We have to find the Temperature at which reaction would be spontaneous.

For spontaneous reaction : \triangle G = negative (-)

For non-spontaneous reaction : \triangle G = positive (+)

We can find the temperature using the formula for Gibbs free energy which is:

\triangle G = \bigtriangleup H - T\bigtriangleup S

Where, G = Gibbs free energy ,

H = Enthalpy

S = Entropy

T = Temperature

By plugging the value of G , H and S in the above formula we can find 'T'

\triangle G = \bigtriangleup H - T\bigtriangleup S

Since reaction should be spontaneous that means \triangle G should be negative , so the above formula can be written as :

\triangle G < \bigtriangleup H - T\bigtriangleup S

On rearranging the above formula we get :

0 < \bigtriangleup H - T\bigtriangleup S

T < \frac{\bigtriangleup H}{\bigtriangleup S}

T < \frac{-92\frac{KJ}{mol}}{-0.199\frac{KJ}{mol.K}}

T < (\frac{-92}{-0.199})\times (\frac{KJ}{mol})\times (\frac{mol.K}{KJ})

T < 462.3 K

For the reaction to be spontaneous , T should be less than 462.3 K, so out of given option , C is correct which is 400 K.

How many atoms are there in 7.6 moles of Iron?
Harlamova29_29 [7]

Answer:

45.77 × 10²³ atoms

Explanation:

Given data:

Number of moles of iron = 7.6 mol

Number of atoms = ?

Solution:

Avogadro number:

The given problem will solve by using Avogadro number.

It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.  The number 6.022 × 10²³ is called Avogadro number.

1 mole = 6.022 × 10²³ atoms

7.6 mol  ×  6.022 × 10²³ atoms / 1 mol

45.77 × 10²³ atoms
