Chemical Industry Flashcards
The order of a reactant can only be determined with___
Experimental data
If doubling a reactant concentration doubled rate of reaction, what is the order?
first order
what is rate of reaction usually measured in?
moldm-3s-1
Rate of reaction is the gradient of what graph
concentration-time
what happens to the rate constant as temperature increases
it also increases
out of reactants, products, and catalysts, what can rate equations contain?
reactants and catalysts
give an expression to mathematically represent the fact a reactant is first order
rate = k[A]
where A is the reactant
Give an expression to mathematically represent the fact a reactant is second order
rate = k[A]2
What is overall order
the sum of the individual orders
what is a rate constant unique to
a specific reaction at a specific temperature
if doubling a reactant concentration quadruples rate of reaction, what is the order
second order
define rate determining step
the slowest step in the mechanism
