At what temperature will the following reaction happen spontaneously, given that ΔH = 8.91×103 J/mol and ΔS = –219.20 J/mol·K? C
Scrat [10]
In order for a certain reaction to be spontaneous, the change in Gibb's free energy must be negative, that is:
dG < 0

We can calculate dG using:
dG = dH - dS

When we plug in the given values, we see that the sign of dG will never be negative; therefore, the reaction will not be spontaneous under any conditions.

Which answer accurately describes the difference between speed and velocity?
irakobra [83]
I think the correct answer from the choices listed above is the second option. The difference between speed and velocity would be that speed <span> requires distance. Velocity requires displacement. Speed only has a magnitude while velocity is a vector quantity which means it has direction and magnitude.</span>

A sample of argon gas occupies a certain volume at 11°C. At what temperature would the volume of the gas be three times as big?
stiv31 [10]
V₁/T₁ = V₂/T₂ = const

T₁=11+273=284K
V₂=3V₁

V₁/T₁=3V₁/T₂

T₂=3T₁

T₂=3*284=852K

t₂=852-273=579°C
