The enthalpy of vaporization of ethyl acetate is 31.9 kj/mol at its normal boiling p point. The b.p is 77.2 C.
The enthalpy of vaporization, also known as the (latent) heat of vaporization or heat of evaporation, is the quantity of energy (enthalpy) that must be added to a liquid substance in order to transform a portion of that substance into a gas. The enthalpy of vaporization depends on the pressure at which the transformation takes place. The normal boiling point of the substance is frequently provided along with the enthalpy of vaporization. The inaccuracy in the measured value is frequently smaller, even though tabulated values are typically corrected to 298 K. The larger internal energy of the vapor phase relative to the liquid phase, in addition to the work against air pressure, equals this. The increase in internal energy could represent the energy required to overcome intermolecular interactions in the liquid (or solid, in the case of sublimation). The extremely low enthalpy of vaporization of helium, which is 0.0845 kJ/mol, is a result of the weak van der Waals interactions between its atoms. However, the energy required to heat the same amount of water from 0 °C to 100 °C (cp = 75.3 J/Kmol) is more than five times more than the enthalpy of vaporization of liquid water, which is 40.65 kJ/mol.

Justify your answer (c) A student claims that cl2 is a catalyst in the reaction. Explain why the students claim is false.
A. We are aware that the reaction's rate depends on the slowest, or rate-determining, step in the overall reaction mechanism. The first step of the reaction is the one that moves the most slowly in the example reaction mechanism. As a result, just one step (Step 1) would have an impact on the reaction's rate.
As a result, the rate law for the mechanism described is given by –
Step 1. Cl2 2Cl (slow) ---------k1
Step 2. Cl + C5H10HCl + C5H9 (fast) ---------k2
Step 2. C5H9 + Cl C5H9Cl (fast) ---------k3

0.161 mole of gas present in the the mixture of ch4 and o2 of volume 10.5l . This is calculated using the Dalton's law of partial pressure and Ideal gas equation.
Partial pressure of the gas is derived by Dalton's law of partial pressure. Dalton's law of partial pressures states that the total pressure of a mixture of gases is equal to the sum of the partial pressures of the component gases. The partial pressure of ch4 is 0.175atm and the partial pressure of o2 is 0.250. we can calculate the total pressure.
Partial pressure CH4 = 0.175 atm.
Partial pressure O2 = 0.250 atm.
Total pressure = 0.175 atm. + 0.250 atm. = 0.425 atm.
mole fraction CH4 = 0.175/0.425 = 0.412
mole fraction O2 = 0.250/0.425 = 0.588
The mixture occupies a volume of 10.5l at 65 degree.so, we can use here the ideal gas equation. It is the equation of state of a hypothetical ideal gas.

Using the following equation for the combustion of octane, calculate the heat of reaction for 50.00 of octane. The molar mass of octane is 114.33 .
When the heat of reaction is applied to 50 octane, the heat of reaction is -2407.43 KJ. Octane has a molar mass of 114.33.
Explain about the octane?It's important not to confuse octane with the octane number assigned to gasoline because octane is a hydrocarbon with an eight-atom chain. The antiknock characteristics of fuels are compared using the octane rating system, which uses a scale with 0 being pure n-heptane and 100 being pure 2,2,4-trimethylpentane (isooctane, an isomer of octane).
When a fuel is burnt in a mixture with air in the cylinder of an internal combustion engine, its capacity to withstand knocking is measured by its octane number, often known as its antiknock rating.
The liquid n-octane has the smell of gasoline and is colorless. Both less dense and insoluble in water as a result, floats on water. In order for modern engines to operate correctly, octane, a fuel additive, is required.
Octane weight is 50 g.
Octane's molecular weight is 114.33 g/mole.
We must first determine the octane molecular weight.
= 50/114.33g/mole.
