1
Q
average Rate equation
A
-Change in conc / time
delta [x] / delta t
2
Q
Rate definition
A
-Speed at which reactants are converted to products overtime
3
Q
Instantaneous rate
A
-Slope of tangent line
-1 point on curve
-2 points on tangent line to calculate
slope = y2-y1 / x2-x2
-Reaction rate at a specific time
4
Q
Instant rate
A
-At time 0, how fast the reaction is
-When the reaction is the fastes
-Tangent at time 0
5
Q
Sign reactants in rate
A
Always negative because its being used up
6
Q
Units of rate constant
A
-Exponent + sec always overall order
-In denometer its positive, written out its negative
7
Q
How to relate rate of appear/dissapear to others in same reaction
A
-Stoichimetric coeffecients
