| 66554043 | What two factors are necessary for a spontaneous reaction to occur? | 1.) - Change of heat=exothermic (enthalpy) 2.) + Change of heat(S)=entropy (disorder, chaos) | |
| 66554044 | How can entropy be increased? | Increase temperature, more products then reactants, dissolve solute in solvent, gases=most entropy | |
| 66554045 | What two factors allow for a more effective collision? | 1.) enough kinetic energy 2.) proper orientation (- & +) | |
| 66554046 | List the fice factors that can affect the rate of reaction. | 1.) catalyst 2.) surface area 3.) temperature (high) 4.) concentration 5.) nature of reactANTS | |
| 66554047 | What two things does a catalyst do? | Lowers activation energy and speeds up the reaction | |
| 66554048 | LeChatlier's 4 stresses...? | 1.) concentration(molarity) 2.) temperature 3.) pressure 4.) catalyst |
