Answer: New absolute pressure is
Explanation:
Gay-Lussac's Law:
This law states that pressure is directly proportional to the temperature of the gas at constant volume and number of moles. As the gas is enclosed in a rigid metal container the volume of the gas is fixed.
(At constant volume and number of moles)
Given:
When you say the solution is hypertonic, it means that the solution has a higher osmotic pressure. The formula for this is:
P = iMRT,
for strong electrolytes, i = number of ions.
for nonelectrolytes, i = 1
1. The P for sucrose solution which is a nonelectrolyte (assuming room temp):
P = (1)(1m)(8.314 J/mol-K)(298 K)
P = 2477.572 Pa
The P for NaCl solution, which is a strong electrolyte:
P = (2)(1 m)(8.314)(298 K)
P = 4955.144 Pa
<em>So, that means that NaCl is more hypertonic than the sucrose solution.</em>
2. For the second question, the P for the combination of 1 m glucose (nonelectrolyte) and 1 m sucrose is:
P = (1)(1 m)(8.314)(298 K) + (1)(1)(8.314)(298 K) = 4955.144 Pa
<em>In this case, the osmotic pressures are now equal. It is not hypertonic, but isotonic.</em>
Keq= (products)/ (reactants)
Keq= ( [NO]^2 x [Cl2]) / ( [NOCl]^2)
Keq= ( (0.02)^2 x (0.01) ) / (0.5)^2= 1.6 x 10-5
