Textbook Problem

Now compare the fuels on an energy-equivalent basis. What volume of ethanol would have to be burned to get the same energy as 1.00 L of octane? When you burn enough ethanol to have the same energy as a liter of octane, which fuel produces more CO2?

Interpretation Introduction

Interpretation:

The volume of ethanol would have to be burned to get the same energy of an octane and the fuel which reduces more CO2 has to be identified

Concept Introduction:

Heat energy required to raise the temperature of 1g of substance by 1k.Energy gained or lost can be calculated using the below equation.

  q=C×m×ΔT

Where,

  q= energy gained or lost for a given mass of substance (m),

  C =specific heat capacity

  ΔT= change in temperature

Explanation

Let x be the volume of ethanol

Given value of one liter of octane is 3.106×104kJ (From Question 99074-5.2-2Q)

Given value of one liter of ethanol is 2.105×104kJ (From Question 99074-5.2-2Q)

Volume of ethanol needed =2.105×104kJ/LC2H5OH×x =3.106×104kJ

Solving for x, we get,

x=1
