Q1
For a reaction with a rate constant k, what is the relationship between the rate of reaction and the concentration of reactants for a first-order reaction?
Rate = k[A]^2
Rate = k[A]
Rate = k[A]^3
Rate = k[A]^0
Questions & Step-by-Step Solutions
For a reaction with a rate constant k, what is the relationship between the rate of reaction and the concentration of reactants for a first-order reaction?
Step 1: Understand that a first-order reaction means the rate depends on the concentration of one reactant.
Step 2: Identify the reactant in the reaction, which we will call [A].
Step 3: Know that the rate of the reaction is how fast the reactants turn into products.
Step 4: Learn that for a first-order reaction, the rate is calculated using the formula: Rate = k[A].
Step 5: Recognize that 'k' is the rate constant, a number that helps determine the speed of the reaction.
Step 6: Understand that if the concentration of [A] increases, the rate of the reaction also increases.
Step 7: Conclude that the relationship is direct: as [A] goes up, the rate goes up.
First-Order Reaction – In a first-order reaction, the rate of reaction depends linearly on the concentration of one reactant.
Rate Constant (k) – The rate constant is a proportionality factor that relates the rate of reaction to the concentration of reactants.
