Rates Flashcards
How do you deduce the rate constant?
Experimental data is required by changing the concentration of one reactant at a time in an experiment
On a concentration against time graph how do you find the rate of reaction?
Find the gradient at a given point
Half life
the time take for the concentration for reactants to reduce by a half
what does [A]^0 mean in a rate equation?
It is zero order and the concentration decreases at a constant rate
what does [B]^1 mean in a rate equation?
It is first order and concentration halves at a constant rate
what does [C]^2 mean in a rate equation?
It is second order. at first the concentration decreases rapidly then it decrease slowly
How can a balanced symbol equation help deduce the rate equation?
Stoichiometry relates to the order of reaction
rate of reaction
The rate of change of the concentration of reactants into products
Rate determining step
the slowest step of the reaction
What affects the rate constant k?
Temperature and use of a catalyst
what affects Kc (equilibrium constant)
Temperature only
what is Kc and what is its equation?
[products]/[reactants]
equilibrium constant
