39that actual energy wala, even i have doubt, i think my sir has given a great explanation for it, i will see to my book and post it later.

seond order reaction....when base catalysed

what are the orders of rxn that arrhenius eq is applicable
A 0
B 1
C 2
D 3
E [5]
11I don't think there is any limit to that order for arrhenius equation to be applied????
9yes Arrhenious eq is applicable to all orders
( some confuse it with 1st order only )
11I thought it was applicable to all orders?? Any confusion regarding that??
39here it cannot accept photon. therefore the electron will not get excited a all.
i mean it should accept the photon of exact energy or it will not accept at all.
dont confuse with photoelecric effect
9A small sub atomic particle was passed thru a watertank of Cd , existence of it was inferred when 2 γ rays and a neutron was captured by Cd.
Wats the particle ??
ansneutrino
9but then wont it go to 2 and release xtra energy as photon ?
106false.........
hehe just to contradict vishal but i think i have a reason
9yes its false according to BT study material can u explain how ?
3it cant be possible according to plank uncle it has to be integral values!!!
but wat i cant understand is wat will happen to it !!!!!!!
106yes energy is quantised... so it just needs the exact amt. of energy to go to any particular energy level... so, if its provided energy that's not equal to that exact energy, it will not go anywhere...
9someone pls give a detailed ans ?
this q has shaterred some of my basics ;(
106chhalo manish bhaiyya ya nishant bhaiyya se poochte hain..... im also not convinced of my answer.
3no something has to happen ashish where will all that energy vanish..... but 1 things sure it wont go to n=2
