Rate Equations
Flashcards do conjunto (8)
- 1What do rate equations tell you?How the rate is affected by the concentrations of reactants
- 2What is the rate equation for the general equation: A + B --> C + DRate = k[A]ᵐ [B]ⁿ
m and n are orders of reaction
k is the rate constant - 3TRUE OR FALSE: The units of k varyTRUE
- 4TRUE OR FALSE: The rate constant of a first order reaction is equal tot he gradient of the rate-concentration graph of that reactantTRUE
- 5What is half-life (of a reaction)?The time it takes for half of the reactant to be used up. It can be calculated from a concentration-time graph
- 6TRUE OR FALSE: The half-life of a zero order reaction is independent of the concentration.FALSE
The half-life of a FIRST order reaction is independent of the concentration - 7Given the half-life of a first order reaction, what is the equation used to work out k?
- 8What are the units of k for first order reactions?s⁻¹
