Answer: The pressure of nitrogen will be 2.0 atm
Explanation:
According to ideal gas equation:
P = pressure of gas = 1.0 atm
V = Volume of gas = 10.0 L
n = number of moles = ?
R = gas constant =
T =temperature =
Now again using ideal gas equation :
Thus pressure of nitrogen will be 2.0 atm
Answer:3480s⁻¹
Explanation:We can solve the following problem using the Arrhenius equation.
Arrhenius equation is given by:
A=Pre-exponential factor or frequency factor
Ea=Activation energy
R=Ideal gas constant
T=Temperature
K=Rate constant
From the Arrhenius equation we can see that the rate constant K is related with the activation energy and frequency factor.
In the question we are given with the following data:
Ea=42KJ/mol=42x 1000 J/mol
A=8.0×10¹ per second
T=298K
R=8.314J/K mol
when we substitute these given values in Arrhenius equation
K=3480s⁻¹
The value of rate constant obtained is 3480s⁻¹.
