What are energy profile diagrams?Show answer
An energy profile plots the energy of the chemicals as the reaction proceeds (reactants on the left, products on the right):
What is q1?Show answer
State whether a reaction that makes its surroundings colder is exothermic or endothermic. [1 mark]
What is q2?Show answer
On an energy profile, state where the products lie relative to the reactants for an exothermic reaction. [1 mark]
What is q3?Show answer
