Whether you are stuck on Part 1 (Equilibrium Quantities) or wrestling with partial pressures in Part 2, Part 1: Equilibrium Quantities Before calculating Kpcap K sub p

, you must find the moles of each species at equilibrium. This usually involves a "Reaction Table" (or ICE table). Example 1: Methane and Steam

CH4(g)+H2O(g)⇌CO(g)+3H2(g)cap C cap H sub 4 open paren g close paren plus cap H sub 2 cap O open paren g close paren is in equilibrium with cap C cap O open paren g close paren plus 3 cap H sub 2 open paren g close paren Initial Moles Equilibrium Moles CH4cap C cap H sub 4 2.4 H2Ocap H sub 2 cap O 1.4 COcap C cap O 0.6 H2cap H sub 2 1.8 Logic: If COcap C cap O increases by 0.6 moles, H2cap H sub 2 must increase by moles due to the stoichiometry.

Common Mistakes in Chemsheets A2 1079 Answers

Over the years, examiners and teachers have noted recurring errors when students complete this worksheet:

Forgetting the acid catalyst in nitration (H₂SO₄ is not just a drying agent – it generates NO₂⁺).
Using KMnO₄ to oxidize benzene rings – benzene is unreactive to oxidation; side chains oxidize, not the ring.
Confusing acylation with alkylation – Friedel-Crafts acylation (AlCl₃, RCOCl) gives ketones; alkylation (AlCl₃, RCl) gives alkylbenzenes.
Ignoring directing effects – Not all substituents are equal; NH₂ and OH are 2,4-directors; NO₂ and COOH are 3-directors.
Drawing curly arrows incorrectly – Arrows must start from a bond (not an atom) and end at an atom or bond.

1. Ligand Exchange Equations

Students often struggle with the stoichiometry of exchange. For example, exchanging water ligands for ammonia or chloride ions requires careful balancing of charges and ligand ratios.

The Trap: Forgetting that chloride ions (Cl⁻) are larger than water molecules, often leading to a coordination number change from 6 to 4 (tetrahedral).

How to Find Official Chemsheets A2 1079 Answers

Chemsheets is a copyrighted resource created by a UK-based educator. The official answers are not freely distributed on the public internet. Instead, they are provided to teachers and tutors who purchase the materials. As a student, your best sources for legitimate answers are:
