chamical eq dbts

for question 1 i thnk d ans is (d)

i said naa its more than one correct

Q2. CH3COOH2+ i.e. CH3COOH+(H+) .. addition of H+ is equivalent to removal of OH- .. so Ch3CooH2+ si the conjugate acid of CH3COOH

CH3COOH2+ removal of H+ --> CH3CoOH so CH3COOH is conjugate base of CH3COOH2+

HF removal of H+ --> F- so F- is conjugate base of HF

So, only (a)

Q1. (not in syllabus)

arre yehi to dbt hai
ans 2 is given as b,c,d which i am sure is wrong.....isnt it ?

are u sure the question was which of them are correct or which of them are worng?

at a given temperature, rate of a reaction is directly proportional to the active mass of the reactant
active mass = concentration * activity coefficient
=>a=c*f
(f) is a measure of non ideality , for ideal system f=1
for ideal solution, a=[molar concentration]
for pure liquid and solid, a=1
for ideal gas,a=partial pressure

ans-1) it should be a) only as in other cases it is only valid for ideal solutions.

ans-2)it should be a) only as HF is stonger than acetic acid.

ans1=a,b

ans sorry i misread the ques2...it is "incorrrect" and not "correct"
