degree of dissociation means how much amount of products are formed and how much reactants is dissociated

At STP the moles = V/22.4 Hence moles would constant in both phases and hence the volume of two would be the same too with no change.
To prepare 100ml of 6M acid => moles would be = > 6 x 100/1000 = > 0.6 And 69% by weight, Volume = mass/density => 69/1.41 = > 48.936 ml moles => 0.6 = weight/63 Weight = 378/10 = > 37.8 gms.
Already answered your qstn. as u have asked twice. Plz check your previous qstn . The answer would be: See first U would need to check the coefficients of the fully Balanced reaction. In case of HI...
Hi Divya, Your doubt is obvious. See first U would need to check the coefficients of the fully Balanced reaction. In case of HI the balanced eqn. is 2HI ↔ H2 + I2 a(1-x) ax/2 ax/2 and that is so the...
Remaining parameters that is Temperature, moles to be constant. From Boyle’s law, P1V1 + P2V2 = PV Hence, 750*1.5 + 100*2 = P*5 200 + 1125 = 5P P = 1325/5 = 265 mm.
From the definition, d[A]/dt = -k[A]^2 where [A] is the initial conc. Now integerating both sides with suitably measures, d(A)/(A)^2 = -kdt -[(1/At – 1/A0)] = -kt or [(1/At – 1/A0)] = kt + c For...
Kinetic gas eqn. PV = nRT and K = 3KT/2. Boyle’s law => PV =constant that is at constant temperature, P1V1 = P2V2 Charle’s Law => Presuure is constant that is = V1/T1 =V2/T2
The faraday’s laws of eqns. were experimentally derived that is acc. to the definition from the Faraday’s first law it is: The amount of substance deposited on electrode would be directly...
@ ajith physical chemistry can be defined as the study of chemistry which deals with physical problems or problems from physics , this generally involves the calculation part of chemistry , and...
An electrochemical cell is a device capable of either generating electrical energy from chemical reactions or facilitating chemical reactions through the introduction of electrical energy. A common...
A battery or galvanic cell stores energy in chemical form in its active materials and can this convert this to electrical energy on demand, typically by means of an electrochemical...
@ ebin i can help u with the correct approach to this question , rest u have to only put value and solve it . apply the following formula K = 2.303 / t log [ initial concentration } / [ final...
since in 30 minutes 10 gram degrees to 5 gram and in 60 minutes it decreases to 2.5 gram and then in 90 minutes to 1.25 gram...... hence we find a uniform decrease which is only in the case of a first...
Already ANswered this: Plz check your previous question, 2BrCl (g) = Br2 (g) + Cl2 (g) t=0 3.3 * 10^-3 0 0 t=t 3.3 * 10^-3 – x x/2 x/2 Kc = x^2/4(3.3 * 10^-3 – x)^2 = 32 x/(3.3 * 10^-3 – x) = 2 x 4 x ...
2BrCl (g) = Br2 (g) + Cl2 (g) t=0 3.3 * 10^-3 0 0 t=t 3.3 * 10^-3 – x x/2 x/2 Kc = x^2/4(3.3 * 10^-3 – x)^2 = 32 x/(3.3 * 10^-3 – x) = 2 x 4 x root(2) x = 37.3 – 11.3x 12.3x = 37.3 x = 3.035 mBar. At ...
Due to synergetic bonding, bond order decreases and hence bond length should increase. It can not increase abnormally and hence a nearby value is option (a)
@ nagarani if we have 3 components in a solution then its called as trinary , solution and if two then binary solution , in the case of 3 components , we bhave mainly 2 solutes as well as 1 solvent...
V/T=constant so, volume will be doubled when temperature will be double. i.e temperature will be 273x2=546K
At eqm. A + B -------> C + D t=teq. 2 2 2 2 t = t’ 2-x 2-x 2+x 2+x Now given x = 1 Hence the moles left after re-eqm. established , t=t’ 1 1 3 3 Hence, Kc = 3*3/1*1 = > 9
From Faraday’s first la, W = Z*Q 5*1930*2 = W W = 19300 gm or 19.3 kgs. Z =2 as the CuSO4 has the valence factor as 2.
Calculate the valence factor for the Oxygen first. That would be => V.F = 2. Hence, Equivalent Weight of Oxygen is => 32/2 = 16
