TASKS FOR THE SUMMATIVE ASSESSMENT FOR THE TERM 2
Summative assessment for the chapter 10.2 A “Introduction to thermodynamics”
Learning objectives 10.3.1.2 Understand that chemical reactions include processes of
bond breaking and formation of new chemical bonds
10.3.1.3 Determine experimentally the change in the reaction
enthalpy and calculate it based on reference data
10.3.1.4 Explain the physical meaning of the Hess’s Law and to
use it to calculate changes of enthalpy of chemical
reactions
10.3.1.6 Explain the change in Gibbs free energy and calculate it
based on reference data
10.3.1.7 predict a spontaneous reaction behaviour by
thermodynamic data
Assessment criteria A learner
Use mean bond enthalpies to calculate an approximate
value of ΔH for reactions in the gaseous phase
Determine the experimental change of reaction enthalpy
and calculate it based on reference data
Explain the physical meaning of Hess's Law and be able to
use it to calculate changes of enthalpy of chemical reaction
Explain the balance between entropy and enthalpy which
determine the feasibility of a given reaction
Predict a spontaneous reaction behaviour by
thermodynamic data
Level of thinking skills Application
Higher order thinking skills
Duration 25 minutes
Tasks
1. The table below contains some mean bond enthalpy data.
