FACTORS AFFECTING THE RATE OF REACTION Flashcards
ON WHAT FOUR THINGS DOES THE RATE OF REACTION DEPEND ON
1) TEMPERATURE
2) THE CONCENTRATION OF A SOLUTION ON THE PRESSURE OF GAS
3) SURFACE AREA- DEPENDS ON SIZE OF THE LUMPS OF A SOLID
4) THE PRESENCE OF A CATALYST
WHEN TEMPERATURE IS INCREASED (…)
PARTICLES MOVE FASTER (MORE COLLISIONS)
HIGH TEMEPRATURE ALSO INCREASE THE (…) SINCE PARTICLES ARE MOVING FASTER
ENERGY
REACTIONS ONLY HAPPEN IF PARTICLES HAVE ENOUGH (…)
ENERGY
THE HIGHER THE TEMPERATURES THERE WILL BE MORE (…) SO INCREASING THE TEMPERATURE INCREASES THE RATE OF REACTION
SUCCESSFUL COLLISIONS (MORE PARTICLES COLLIDE WITH ENOUGH ENERGY TO REACT)
INCREASING CONCENTRATION OR PRESSURE INCREASES THE (…)
RATE
IF A SOLUTION IS MADE MORE CONCENTRATED IT MEANS THERE ARE MORE (…)
PARTICLES OF REACTANT IN THE SAME VOLUME
MORE PARTICLES OF REACTANT IN THE SAME VOLUME MAKES (…)
COLLISIONS MORE LIKELY, SO THE REACTION RATE INCREASES
SMALLER SOLID PARTICLES (MORE SURFACE AREA) MEANS A (…)
HIGHER RATE
IF ONE REACTANT IS A SOLID, BREAKING INTO SMALLER PIECES; IT WILL (…)
INCREASE THE SURFACE AREA TO VOLUME RATIO (MORE OF THE SOLID WILL BE EXPOSED, COMPARED TO ITS OVERALL VOLULE)
IF THE SUIRFACE AREA INCREASES; THE PARTICLES WILL HAVE (…) SO THE (…) WILL INCREASE
MORE SURFACE AREA TO WORK ON/FREQUENCY OF COLLISIONS
THE RATE OF REACTIONS IS FASTER FOR SOLIDS WITH A (…)
LARGER SURFACE AREA TO VOLUME RATIO
CATALYSTS (…) THE RATE OF A REACTION
INCREASES
USING A CATALMUYST WONT CHANGE THE PRODUCTS OF THE REACTION; SO TH (…) WILL STAY THE SAME
EQUATION
SINCE IT ISNT USED UP, YOU ONLY NEED A (…) TO CATALYSE LARGE AMOUNTS OF REACTANTS
