Answer:
The molar mass of the gas is 90.4g/mol
Explanation:
To solve this question we have to use the equation:
d = PM / RT
<em>Where d is density of the gas = 2.29g/L</em>
<em>P is pressure = 0.75atm</em>
<em>M is molar mass of the gas = ??</em>
<em>R is gas constant = 0.082atmL/molK</em>
<em>T is absolute temperature = 88°C + 273.15 = 361.15K</em>
<em />
Solving for M:
dRT / P = M
2.29L*0.082atmL/molK*361.15K / 0.75atm = M
90.4g/mol = M
The molar mass of the gas is 90.4g/mol
Answer:
The activation energy of the reaction is 1.152 kJ/mol.
Explanation:
Activation energy is the minimum amount which is absorbed by the reactant molecules to undergo chemical reaction.
Initial temperature of reaction =
Final temperature of reaction =
Initial rate of the reaction at 100 k =
Final rate of the reaction at 200 k =
Activation energy is calculated from the formula:
R = Universal gas constant = 8.314 J/ K mol
