(ii) Indicate whether the root-mean-square speed of the CO₂(g) molecules is greater than, equal to or less than the root-mean-square speed of the CO(g) molecules. Justify your answer.
If you have a specific 1972 question in mind (or a topic you remember), paste it here and I’ll walk through the solution step-by-step.
ΔG∘=57.9 kJ/molcap delta cap G raised to the composed with power equals 57.9 kJ/mol :Rearrange the Gibbs free energy formula ( ) to solve for enthalpy.
For modern students, the 1972 free response section is a fascinating fossil. Before the era of calculators, data tables, or multiple-choice-heavy scoring, the 1972 exam was a raw, computational beast. It didn't test conceptual understanding as much as it tested mathematical endurance .
However, the Below is a reconstructed guide based on the archived curriculum and common problems referenced in AP history.
The user wants a long article for the keyword "1972 ap chemistry free response answers". The article should provide the answers. I will structure the article as follows: an introduction, a note on the exam's context, the free-response questions with answers and explanations, a study strategy section, and a conclusion.
The exam often featured questions regarding the relationships between , , , and the equilibrium constant (
Students were typically asked to calculate the degree of dissociation and the equilibrium constant Kpcap K sub p for the reaction:
