Consider the following reaction where kc = 9.52×10-2 at 350 k. ch4(g) + ccl4(g) 2ch2cl2(g)a reaction mixture was found to contain 2.18×10-2 moles of ch4(g), 3.79×10-2 moles of ccl4(g) and 1.09×10-2 moles of ch2cl2(g), in a 1.00 liter container. is the reaction at equilibrium? if not, what direction must it run in order to reach equilibrium? the reaction quotient, qc, equals .the reactiona. must run in the forward direction to reach equilibrium. b. must run in the reverse direction to reach equilibrium. c. is at equilibrium.

The reaction is not at equilibrium and reaction must run in reverse direction.

Explanation:

At the given interval, concentration of =

Concentration of =

Concentration of =

Reaction quotient, , for this reaction =

species inside third bracket represents concentrations at the given interval.

So,

So, the reaction is not at equilibrium.

As, therefore reaction must run in reverse direction to reduce and make it equal to .

2b2t

explanation:

2b2t

percent abundance for cu-63 can be shown as:

63 x + 65 (1-x) = 62.9296

65 - 62.9296 = 2 x

x = 1.035

thus, percent abundance for cu-63 is 1.035

percent abundance for cu-65 can be shown as:

63 x + 65 (1-x) = 64.9278

65 - 64.9278 = 2 x

x = 0.0361

thus, percent abundance for cu-63 is 0.0361

the mass spectrum of cu-63 showing the intense peak as, this isotope is found in nature more abundantly around 92.38 % in comparison to cu-65 which is found 62.58 % naturally
