Chapter 9: Q84E (page 343)

Explain the advantages and disadvantages of hydrogen as an alternative fuel.

Short Answer

Expert verified

Hydrogen gas is environment friendly, but expensive for production

Step by step solution

01

Advantages of hydrogen fuel

The advantages of hydrogen as an alternative fuel are,

Hydrogen is environment friendly. When hydrogen gas is burnt in the air, it only produces water. Hence, it is cleanest fuel and does not cause pollution.
Hydrogen is renewable energy. It can be renewed by decomposition of the water.
It is also used in the rockets as fuel. It is more powerful than gasoline.

02

Disadvantages of hydrogen fuel

The disadvantages of hydrogen as an alternative fuel are,

Hydrogen is expensive. It can be produced by electrolysis of water that requires electricity. As, electricity is costly. So, the production of hydrogen gas is expensive.
Storage of hydrogen gas is hard.
Hydrogen gas is highly inflammable.

Calculate for the reaction:

Based on enthalpy change, is this a useful reaction for the synthesis of ammonia?

Calculate the energy required to heat 1.00 kg of ethane gas $(C_{2} H_{6})$ from $25.0 ° C t o 75.0 ° C$ first under conditions of constant volume and then at a constant pressure of 2.00 atm. Calculate $∆ E, ∆ H$ , and w for these processes also.

Assuming gasoline is pure $C_{8} H_{18} (L)$ predict the signs of qandw for the process of combusting gasoline into ${CO}_{2} (g)$ and $H_{2} O (g)$ .

Question : Given the following data:

$C_{2} H_{2} (g) + 5 / 2 O_{2} g \to 2 {CO}_{2} g + H_{2} O ∆ H = - 1300 kJ C (s) + O_{2} (g) \to {CO}_{2} (g) ∆ H = - 394 kJ H_{2} (g) + 1 / 2 O_{2} (g) \to H_{2} O (l) ∆ H = - 286 kJ$

Calculate ∆H for the reaction

$2 C (s) + H_{2} (g) \to C_{2} H_{2} (g)$

Some automobiles and buses have been equipped to burn propane $(C_{3} H_{8})$ as a fuel. Compare the amount of energy that can be obtained per gram of $C_{3} H_{8} (g)$ with that per gram of gasoline, assuming that gasoline is octane $[C_{8} H_{18} (l)] .$ (See Example 9.8.) Look up the physical properties of propane. What disadvantages are there to using propane instead of gasoline as a fuel?
