N2 + H2 -> NH3
They both have 2s after them because they are both diatomic molecules
If the temperature increases the pressure increases. If the temperature decreases the pressure decreases I hope this helped
<h3>The temperature is 15.58 kelvin </h3>
<em><u>Solution:</u></em>
<em><u>Ideal gas equation is given as:</u></em>

Where,
P = pressure
V = volume
n = amount of substance
R = ideal gas constant
T = temperature
From given,
V = 120 liters
n = 5 moles

P = 5.4 kPa
T = ?
Therefore,

Thus the temperature is 15.58 kelvin
Answer:
(1) 0.0016 mol/L
Explanation:
Let the concentration of alcohol after 3.5 hours be y M
The reaction follows a first-order
Rate = ky^0 = change in concentration/time
k = 6.4×10^-5 mol/L.min
Initial concentration = 0.015 M
Concentration after 3.5 hours = y M
Time = 3.5 hours = 3.5×60 = 210 min
6.4×10^-5y^0 = 0.015-y/210
y^0 = 1
0.015-y = 6.4×10^-5 × 210
0.015-y = 0.01344
y = 0.015 - 0.01344 = 0.00156 = 0.0016 mol/L (to 4 decimal places)
