aommaster Posted March 16, 2004 Posted March 16, 2004 I was thinking about factors that affect the rate of reactions So far, i know about: -Catalysts -Surface area -Concentration or pressure -Temperature Are there any others? Please give examples in which they occur. Thanx alot guys!

Sayonara Posted March 16, 2004 Posted March 16, 2004 Shake it, shake it, shake it like a polaroid picture.

aommaster Posted March 16, 2004 Author Posted March 16, 2004 Hold, on i think i got it! Are u trying to say whether the solution is shaken or not?
aommaster Posted March 16, 2004 Author Posted March 16, 2004 Yay!! !i am finally beginning to undersand u guys! Are there any others?
YT2095 Posted March 17, 2004 Posted March 17, 2004 wouldn`t agitation be a function of surface area, making a greater quantity of surfaces available at any given time?
aommaster Posted March 17, 2004 Author Posted March 17, 2004 Well, it may. This won't work however if the solid is completely submerged in the solution. Is light a factor?
YT2095 Posted March 17, 2004 Posted March 17, 2004 there are many reactions that light can be used to either trigger a reaction or catalyse
YT2095 Posted March 17, 2004 Posted March 17, 2004 ok, how about silver chloride, it`s pure white until it`s exposed to light, then it goes a grey/black, same with Gold Chloride, that goes a few different colors but mainly a dark purple. both of these an others are used in photographic film. Hydrogen and Chlorine gas, mixed and left in the dark is quite safe, put it in the light and BANG!
aommaster Posted March 17, 2004 Author Posted March 17, 2004 Thanx YT! Someone was also telling me about fibreglass. Is there any relevance?
YT2095 Posted March 17, 2004 Posted March 17, 2004 not that I know of? the catalyst for that is usualy a peroxide, that`s not to say that there couldn`t be any light activated forms made? It`s just that I don`t know of any the closest I know of is Photo Etching for circuit boards, the boards are often fiber glass with a copper foil adhesed to one or both sides.
aommaster Posted March 17, 2004 Author Posted March 17, 2004 oh yeah! i use those when i make circuits!
aommaster Posted March 17, 2004 Author Posted March 17, 2004 lol! I just didn't think about it that way! I used that only once to be honest, then, i just used developer solution!
YT2095 Posted March 17, 2004 Posted March 17, 2004 well all those are examples of light being used as a catalyst to lower the Activation energy (I call it Trigger energy sometimes, it means the same). as for agitation, I`m still fairly sure that falls under the surface area catagory though.
Sayonara Posted March 17, 2004 Posted March 17, 2004 YT2095 said in post # :wouldn`t agitation be a function of surface area, making a greater quantity of surfaces available at any given time? True, but if he wants to be thorough he should consider all functions.
YT2095 Posted March 17, 2004 Posted March 17, 2004 actualy with regards to the orginal post, Pressure comes under Temperature rather than concentration
aommaster Posted March 17, 2004 Author Posted March 17, 2004 By the way, how does a catalyst work to speed up a reaction?
