1m sure itz bimolecular
The reaction 2N2O5 <--> 4NO2 + O2 follows Ioder kinetics. Hence the molecularity of reaction is
unimoleqular.
pseudo unimoleqular
bimoleqular.
none of these.
Given that Zn + ½ O2 --> ZnO + 35.28 kj HgO --> Hg + ½ O2 - 9.11 kj so the heat of reaction Zn + HgO --> ZnO + Hg is
26.17 kj
44.39 kj
-44.39 kj
-26.17
Among the following : NaOH, Ca(OH)2, KOH and Zn(OH)2 The weakest base is
NaOH
Ca(OH)2
KOH
Zn(OH)2 xplain with reasons

1damn sure it can't be bimolecular.
ans. is 100% none of these.
wherever that ans. bimolecular is given it is definitely wrong
1sahitya plz hurry.tell the ans. to first one
[6]=feeling sleepy.!!!!!!!!!
11st is -26.17
second is also rite itz bimolecular m sure
itz given in d rextion it self na
i mean they hav gievn balnced rxtions .....so 35....sumthng is d heat gievn out .........
n in d secodn one ....... -9... is d heat gievn 2 carry out d rxtion ie endothrmic ......dats y
pehle meine woh + - i mean balnced rxtion ni dekha i thouht itz geivn as delH .......sorry guys
11st bimolecular
order of rxtion n molecularity r diffrnt........
order is knwn frm xperimantal data ...........
moelclarrity is d no of moles takin part in a rxtion ......
here 2 moles of substnce take part so itz 2 molecularity is 2
