Consider the reaction below. How much heat is absorbed if 5.00 moles of nitrogen react

Chemistry
1 answer:
bekas [8.4K]3 years ago
3 0

Explanation:

The given chemical reaction is:

2 N_2 (g) + O_2(g) -> 2 N_20 (g)  delta Hrxn= +163.2 kJ

When two moles of nitrogen reacts with oxygen, it requires 163.2kJ of energy.

When 5.00 mol of nitrogen requires how much energy?

5.00 mol x \frac{163.2 kJ }{2 mol} \\=408 kJ

Hence, the answer is 408 kJ of heat energy is required.

The relationship between moles and volume, when pressure and temperature of a gas are held constant, is: V/n =
Dvinal [7]

Answer:

If the moles of gas are tripled, the volume must also triple.

Explanation:

According to Avogadro law,

Equal volume of all the gases at same temperature and pressure have equal number of molecules.

The number of moles and volume are directly related to each other. By increasing the number of moles volume also goes to increase with same ratio.

When number of moles decreases the volume also goes to decrease at constant temperature and pressure.

Mathematical expression:

V ∝ n

V = Kn

V/n = k

When volume is changed from V₁ to V₂ by changing the number of moles from n₁ to n₂. Then expression will be,

V₁/n₁ = V₂/n₂
