someone help please!!

[SKA]

can you read this for me (just the Abstract part) and please explain how does the humidity effect the reaction rate?

Yes it does. : )

[Ice.Maiden]

But I'm right. : )

Sorry but I forgot my glasses

yeah,

Increasing the humidity above 7% causes a protective layer of water molecules on the surface of the reactants which prevent the chemical reaction taking place so efficiently .

I ♥ him ^

[carrot99]

apparently it is suggested that multiple layers of water molecules are formed at the TiO2 interface with air, even at low relative humidities. The multiple-layered film of water retards/prevents CB from reaching the reactive TiO2 surface or contacting radical species in the boundary layer.

[Ice.Maiden]

See! Told you I was right. Thanks chuck.

[cazzz1975]

it slows the reaction rate, due to the multi layer of film that is produced as a result of the increase in humidity of 7%

Hey how come I didnt get any 'you have a reply' emails?!

Jeez most of you are useless I'm off to the science section...

Thanks to those who read it though :-D

Difference between affect and effect.
Getting drunk can 'affect' a person's balance. - Cause
Falling over is the 'effect' of too much to drink. - Result.

This only applies in a general everyday usage sense.
There are many more definitions of the two words, and ways of using them - such as -
'personal effects' = personal property
'affected attitude = an attitude of pretence.
As no.knowledge said, it is a minefield.
But for general purposes, remembering 'Cause' and 'Result' can help.
