Adistributor of ball bearings sells packages of "remnant" ball bearings that contain a mixture of copper bearings and titanium bearingsâalong with bearings made of a proprietary alloy of several different metals. although the bearings all have the same diameter, 4.175 mm, the metals from which they are made all have different densities. the density of the proprietary alloy is 5.659 g/cm^3.packages of the remnant bearings are, on average, 30.4 percent copper bearings and 51.2 percent titanium bearings, the remainder being proprietary alloy. using the formula for the volume of a sphere, v = 4/5ïr^3, and the densities of the metals. determine the average mass of a ball bearing in one of the packages.

here we have to get the change of moles on decrease the volume of the reaction in gas phase.

the   per the given options it will decrease by (d) 11-50%

we know, on decreasing the volume of the gas phase reaction the reaction moves to the product side.

the reaction:                     so₂cl₂ (g) = so₂ (g) + cl₂ (g)         total

the moles at equilibrium:   1 - α                 α               α           = 1+α

concentrations:                   1 - α               α               α           = 1 + α

(concentration = moles/volume, as volume is 1 l)

(where α is the degree of dissociation)

now the dissociation constant in terms of concentration is :

=  

or,

or,   = (at v = 1l)

the reaction:                     so₂cl₂ (g) = so₂ (g) + cl₂ (g)         total

the moles at equilibrium:   1 - α                 α               α           = 1+α

concentrations:               (1 - α)/0.5           α/0.5         α/0.5       = (1 + α)/0.5

thus, the dissociation constant in terms of concentration is :

or,  

=  

so, the change of 1 : 1/0.5

or, 1: 2

thus it will decrease by 50%.

or, as per the given options it will decrease by 11-50%

can you attach a picture of the lettuce? : )

b.final

i do not get it   at all
