extent and rate of reaction 1 Flashcards
what is molecular speed proportional to
temperature
what is molecular speed inversely proportional to
Mr
what is collision frequency proportional to
temperature at constant volume and pressure
with increased temperature does viscosity increase or decrease and why
decrease as more KE
resistance is the study of what
ionic motion and inverse of conduction
if there is an increase in cross sectional area of medium does conductance decrease or increase
decrease
as length increases does conductance increase or decrease
decrease
if number of ions present increase does conductance increase or decrease
increase
name the different vibration
symmetrical assymetrical scissoring rocking wagging twisting
rate of reaction=
number of ……../ unit time x
……….. with sufficient energy x
………… with appropriate ………….
collisions
fraction
fraction
orientation
factors affect rate ( 4)
physical state
concentration
temperature
with temperature and rate a graph can be plotted. what is plotted and on which axis
lnk vs 1/k
catalysts will increase Rate of Reaction so Delta G is smaller/ higher
smaller
how do catalysts work
they activate reactant Tm chemistry
stabilise Transition states
different reaction mechanism
how can you measure the rate
gaseous,
spectrophotometric
conductivity
