Predict entropy trend from gas moles
A reaction in a materials-analysis workshop changes from 1 mole(s) of gas to 3 mole(s) of gas. Predict the entropy trend. Use the labelled diagram, graph, or data table before calculating. Enter the answer and choose the interpretation that matches the HL chemistry evidence.
Worked practice: chemistry evidence and answer
Use the chemical evidence first, then enter the result and interpretation that match it.
