  4. Rate is inversely proportional to concentration

Questions & Step-by-Step Solutions

What is the relationship between reaction rate and concentration for a first-order reaction?
  • Step 1: Understand what a first-order reaction is. It means that the reaction rate depends on the concentration of one reactant.
  • Step 2: Know that 'reaction rate' is how fast the reactants turn into products.
  • Step 3: Learn that in a first-order reaction, if you increase the concentration of the reactant, the reaction rate increases.
  • Step 4: Remember that 'directly proportional' means if one thing goes up, the other thing goes up too.
  • Step 5: Conclude that for a first-order reaction, if you double the concentration of the reactant, the reaction rate also doubles.
