CHEM P42 GT and paper discussion

[A star]

this is from oct 12 p42

dude the electrode potential then was positive so it decreased that means in opposite direction it was made more NEGATIVE so if the forward is negative it will be made more POSITIVE

ap k paas coursebook ha???us sa dkh lo jitna reacton backward hoga utni E negative

rogger noris mae yae likha hae

When the concentration of a
product
is decreased, the
reaction will have a greater tendency to
“go” in the forward directi
on. This is reflected in a
greater (more positive) cell potential.

more positive na to mae bhi yahi kah raha hon it will b more positive i chose the value which was more positive than the Eo

yahan cocentration of product ki baat ki gy ha

usma kya likhna tha k compound J shows iodoform test...

us mae jo tm nae secondy alcohol with methyl group banaya tha

us mae jo tm nae secondy alcohol with methyl group banaya tha

usna pucha functional group ka pucha tha phla.....mana methy alcohol likha...ya thk hoga???

usna pucha functional group ka pucha tha phla.....mana methy alcohol likha...ya thk hoga???

functional group mae manae methyleketone aur us sae aglae part mae shayad mae nae ,ethyl alcohol likha tha ab yad nahi sae sae

 

[saadgujjar]

functional group mae manae methyleketone aur us sae aglae part mae shayad mae nae ,ethyl alcohol likha tha ab yad nahi sae sae

is question ma 2 baar functional groups ka pucha tha??i forgot

 

[tanixx]

thats only if the forward reaction is positive.

Bhai he decreased the concentration of reactants not product
If you 're talking about 42 :O

yeah he was just stating the rule. i guess it will be applied the opposite

pta ha....ya mana kahin aur sa quote kia ha

It doesn't make sense bro!
Simply, when the concentration of the reactants decrease in an equilibrium reaction so the reaction follows backward, and if the reaction in the equation like
X+ + 1e====> X, the E^ value must decrease that is it becomes more negative.

What was in question, he told us that E^ for X+/X = -0.03 (I dont remember the exact figure)
so what would be the value when concentration is 1*10-4 mol/dm3. which means the concentration is less than 1 mol/dm3. so this value -0.31 would be more negative.

As -0.03 was Eo the STANDARD value (means at standard condition i-e 1mol/dm3)

 

[saadgujjar]

chem ka p5 solved hota Han?

 

[saadgujjar]

A star ab to ap manlo

yeah read it now . chalo pahlae ghalti milgae , hair hae

what were two reactions in organic chemistry question
one was electrophillic substitution wat was other ??

in reduction of PbCl2 i wrote
Pbcl2 + Fe2+ = Pbcl + Fe3+
is this correct ??
