my confusion is arising from the fact that in my book it is written that
Δ G = -RT ln Keq
Keq=KporKc as the standard state is referred in terms of partial pressure or concentration
Δ G = -RT ln Kp
Δ G = -RT ln Kk
if calculate the value of Keq from the equation Δ G = -RT ln Keq using...
SO2(g)+1/2O2(g)⇌SO3(g);ΔHo=-98.32KJ/mole,ΔSo=-95J/(mole-K).
find Kp at 298 Kelvin?
In given question at first Δ G will be calculated using formula ΔG = Δ H – T x ΔS, by putting the given values in formula we get ΔG = -70.01 kJ/mol.
Then Keq will be calculated using equation = Δ G = -RT ln Keq...
"Vapour density is the density of a vapour in relation to that of hydrogen. It may be defined as mass of a certain volume of a substance divided by mass of same volume of hydrogen.
Vapour density = mass of n molecules of gas / mass of n molecules of hydrogen.
Vapour density = molar mass of gas...
The vapour density of N204 at certain temperature is 30. Calculate the percentage of dissociation of N204 at this temperature. N2O4(g)⇌2NO2(g)?
I am unable to understand the concept behind vapour density of the mixture.
Currently, I understand that
2 x vapour density=molar mass.
Vapour density =...
Suppose a cylinder is launched on a horizontal frictional surface such that it has initial translational velocity v and zero angular velocity .the kinetic friction would be applied between the contact points of the cylinder and the surface, opposite to the direction of the translational motion...
In many of the definition of cross product, I have seen the ##\theta##(angle between the two vector) is in the range of 0≤##\theta##≤π.
The angle between the two vector can be measured in two ways, clockwise and anti-clockwise. The clockwise wise measurement is generally taken to be negative...
The magnitude of cross product is defined of vector A⃗ and B⃗ as |A⃗×B⃗|=|A⃗||B⃗|sinθ where θ is defined as the angle between the two vector and 0≤θ≤π.the domain of θ is defined 0≤θ≤π so that the value of sinθ remains positive and thus the value of the magnitude |A⃗||B⃗|sinθ also remain positive...
My current understanding:
The mass of alpha particle is approximately 7340.6 times higher than the mass of electron.in the gold foil scattering experiment the deflection of alpha particle due to electron is approximately zero.
The reason that is given is that since the electron is much lighter...
But the molecules of ideal does collide with each other. The molecules of ideal gas are dimensionless points, how can these points (molecules of ideal gas) collide.
(The equation of ideal gas is PV=NRT.if P=1atm,N=1mole,T=0°K,R=gas constant then volume = zero. Hence, the volume of an individual molecule of ideal gas is zero)
An individual molecule of ideal gas is assumed to have zero volume. The molecules of ideal gas are assumed to be dimensionless points...
I think friction could appear in the absence of a force. Suppose a cube is sliding on a frictional horizontal surface with momentum p(no external force is being applied on the cube). Friction would still be applied on the cube(opposing the motion of the cube), and thus the cube will stop sliding.
