Interpretation Introduction

Interpretation:

To find the heat effect for isothermal process at 300 K

Concept Introduction:

We find the enthalpy of H2SO4of pure and 25-wt-% from the H-x diagram of H2SO4

Then we find the enthalpy of total solution and then find Q using the below equation,

  Q=m3H3m2H2m1H1

Where,

Mass of H2SO4(100 -wt-%) = m1

Mass of H2SO4, (25-wt-%) = m2

Mass of Total Solution = m3

Enthalpy of H2SO4(100-wt-%) = H1 Enthalpy of H2SO4(25-wt-%) = H2

Enthalpy of % of H2SO4 in total solution = H3
