Determine the volume occupied by 0.352 mole of a gas at 25⁰C if the pressure is 81.8 kPa.
lions [1.4K]
Data:
p (pressure) = 81.8 kPa = 81.8*10³ Pa ≈ 8.07 atm
v (volume) = ? (in L)
n (number of mols) = 0.352 mol
R (Gas constant) = 0.082 (atm*L/mol*K)
T (temperature) = 25ºC converting to Kelvin, we have:
TK = TC + 273 → TK = 25 + 273 → TK = 298

Formula:
p*V =n*R*T

Solving:
p*V =n*R*T
8.07*V = 0.352*0.082*298
8.07V \approx 8.60
V \approx  \frac{8.60}{8.07}
\boxed{\boxed{V \approx 1.06\:L}}

For the reaction x2 + y + z → xy + xz, it is found that doubling the concentration of x2 doubles the reaction rate, tripling the
andre [41]
R=[x2][y] rate law of the reaction
check:
if we double x2,  r(new) =[2*x2][y]=2*[x2]*[y]=2*r
if we triple y,  r(new) =[x2][3y]=3*[x2]*[y]=3*r  
z- no effect, so z is not included
