: Don't just copy the final answer. For organic chemistry, focus on the reaction mechanisms (like the decolorization of bromine in the presence of alkenes) and the specific structural changes.
Some qualitative answers are too terse – e.g., “The yield increases” without explaining why (Le Chatelier’s principle, temperature/pressure effects). A weaker student might need to cross-reference the textbook again. hkdse new chemistry a modern view book 2b answer
What is the rate of reaction? Answer: The rate of reaction is the change in concentration of reactants or products per unit time. : Don't just copy the final answer
