Answer:
1.343 atm
Explanation:
We are given the following;
Pressure, p = ?
Volume v = 27 L
Mass of oxygen = 44.9 g
Temperature, T = 315 K
The formular relating all these variables is the equation;
PV = nRT
where R = gas constant = 0.08206 L atm / mole K
To obtain n, we use;
number of moles, n = Mass / molar mass = 44.9 / 32 = 1.403 moles
From the ideal gas equation;
P = nRT / V
P = 1.403 * 0.08206 * 315 / 27
P = 36.27 / 27 = 1.343 atm
Answer:
I think the answer is D. Temperature affects only the rate of reaction.
