Rates Of Reaction Flashcards
What is the unit for rate?
moldm-³s-¹
How is concentration shown is chemistry?
Square brackets
What is the rate equation in relation to order?
Rate = k [A]m[B]n
What is zero order?
When the rate or concentration is 1. Anything to the power of zero is 1
What is first order?
When the rate or concentration changes by a multiple of 2,3,4 etc…
What us second order?
When rate or concentration changes by being squared or cubed etc
How would you rearrange the rate equation to get a value for k?
k = rate ÷ [A][B]
What does zero order look like on a concentration time graph?
Directly proportional
What does first order look like on a concentration time graph?
