Dehydration of Alcohols yield Alkenes. Depending upon the starting material (alcohols) different alkenes are being formed either by following saytzeff rule or Hoffman rule. In case of Cyclopentanol only one alkene is produced (i.e. Cyclopentene) as shown below.

Calculate ΔHrxnΔHrxn for the following reaction: 3C(s)+4H2(g)→C3H8(l)3C(s)+4H2(g)→C3H8(l) Use the following reactions and given
mihalych1998 [28]

<u>Answer:</u> The \Delta H^o_{rxn} for the reaction is -120.9 kJ.

<u>Explanation:</u>

Hess’s law of constant heat summation states that the amount of heat absorbed or evolved in a given chemical equation remains the same whether the process occurs in one step or several steps.

According to this law, the chemical equation is treated as ordinary algebraic expressions and can be added or subtracted to yield the required equation. This means that the enthalpy change of the overall reaction is equal to the sum of the enthalpy changes of the intermediate reactions.

The given chemical reaction follows:

3C(s)+4H_2(g)\rightarrow C_3H_8(l)      \Delta H^o_{rxn}=?

The intermediate balanced chemical reaction are:

(1) C_3H_8(l)+5O_2(g)\rightarrow 3CO_2(g)+4H_2O(g)    \Delta H_1=-2026.6kJ

(2) C(s)+O_2(g)\rightarrow CO_2(g)     \Delta H_2=-393.5kJ     ( × 3)

(3) 2H_2(g)+O_2(g)\rightarrow 2H_2O(g)     \Delta H_2=-483.5kJ     ( × 2)

The expression for enthalpy of the reaction follows:

\Delta H^o_{rxn}=[1\times (-\Delta H_1)]+[3\times \Delta H_2]+[2\times \Delta H_3]

Putting values in above equation, we get:

\Delta H^o_{rxn}=[(1\times -(-2026.6))+(3\times (-393.5))+(2\times (-483.5))]=-120.9kJ

Hence, the \Delta H^o_{rxn} for the reaction is -120.9 kJ.

A balloon inflated in a room at 24 degree celsius has a volume of 4 L. The balloon is then heated to a temperature of 58 degree
WITCHER [35]

Answer: The new volume of the balloon will be 4.45L

Explanation: We will solve this question through the concept of Charles's law. The law states that the volume of a gas is directly proportional to the absolute temperature, assuming the quantity of gas and pressure remain constant.
