that 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.

ok another one till bhargav brings exp for the 1st q

in hydrolysis in acidic medium which is rate determinant Substrate or H+

what are the orders of rxn that arrhenius eq is applicable

yes b5555 ur right pppphhhh are u sure?

Anirudh Narayanan ·

I don't think there is any limit to that order for arrhenius equation to be applied????

9
Celestine preetham ·

yes Arrhenious eq is applicable to all orders
( some confuse it with 1st order only )

Anirudh Narayanan ·

I thought it was applicable to all orders?? Any confusion regarding that??

ani i told u were right ;)

here 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

A 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 ??

ne exp ????????

its frm yg file

but then wont it go to 2 and release xtra energy as photon ?

false.........
hehe just to contradict vishal but i think i have a reason

9
Celestine preetham ·

yes its false according to BT study material can u explain how ?

asish give ur reason [4]

it cant be possible according to plank uncle it has to be integral values!!!

but wat i cant understand is wat will happen to it !!!!!!!

9
Celestine preetham ·

i think its true but am not sure

106
Asish Mahapatra ·

yes 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...

Celestine preetham ·

someone pls give a detailed ans ?

this q has shaterred some of my basics ;(

Asish Mahapatra ·

chhalo manish bhaiyya ya nishant bhaiyya se poochte hain..... im also not convinced of my answer.

greatvishal swami ·

true

no something has to happen ashish where will all that energy vanish..... but 1 things sure it wont go to n=2

energy is quantised ?? !@!$#%#^

is it ??
