This is an incomplete question, here is a complete question.

Which of the three gases will have the highest average kinetic energy at a given temperature?

A) HBr

B) NO₂

C) C₂H₆

Answer : All three gases will have the same average kinetic energy at a given temperature.

Explanation :

The formula for average kinetic energy is:

K.E=\frac{3}{2}kT

where,

K.E = average kinetic energy

k = Boltzmann’s constant

T = temperature

As we know that, average kinetic energy depends only on the temperature.

As the temperature of the all three gases are same. So, the all three gases will have the same average kinetic energy.

Ni2+(aq) + 6 NH3(aq) ⇌ Ni(NH3)6 2+(aq)
Jet001 [13]

Answer:

a) ΔGº= -49,9 KJ/mol = - 50 KJ/mol

b) The reaction  goes to the right to formation of products

c) ΔG= 84,42 KJ/mol. The direction is to reactive, to the left

Explanation:

a) ΔGº= - RTLnKf

You need to convert Cº to K. 25ºC=298K

Then, ΔGº= - 3,814 J/molK * 298K* Ln(5.6 *10^8)= - 49906 J/mol = -49,9 KJ/mol = - 50 KJ/mol

b) The ΔGº < 0, that means the direct reaction is spontaneous when te reactive and products are in standard state. In other words the reaction goes to the right, to formation of products

c) The general ecuation for chemical reaction is aA + bB → cD + dD. Thus

ΔG=ΔGº + RTLn (([C]^c*[D]^d)/[A]^a*[B]^b)

In this case,

ΔG=ΔGº + RTLn ([Ni(NH3)62+] / [Ni2+]*[NH3]^6 )= 84417 J/mol =84,42 KJ/mol

ΔG >0 means the reaction isn't spontaneous in the direction of the products. Therefore the direction is to reactive, to the left

A gas at constant volume has a pressure of 3.20 atm at 300. K. What will be the pressure of the gas at 290. K?
melomori [17]
  • From the general law of gases: PV = nRT,

where P is the pressure (atm),

V is the volume (L),

n is the number of moles,

R is the general gas constant (8.314 L.atm/mol.K),

T is the temperature in Kelvin

  • at constant volume of the gas: P1T2 = P2T1

P1 = 3.20 atm, T1 = 300 K, T2 = 290 K, P2 = ??

(3.20 atm)(290 K) = P2(300 K)

P2 = (3.20 atm)(290 K)/ (300 K) = 3.093 atm

A car was at rest. It then started moving forward in a straight line. The table shows the change in velocity.
Keith_Richards [23]

Answer:

5 m/s 2

Explanation:

if the car moved from 00 to 1-5 then to 2_10 you can know that it is going up in velocity but 5 a second so 5 m a second. hope this helps
