Answer:

0.015 M

Explanation:

For a first order reaction;

ln[A] =ln[A]o - kt

[A] = final concentration

[A]o =initial concentration

k= rate constant

t= time taken

ln[A] =ln[A]o - kt

ln[A] = ln(0.0500) - 6.7 x 10-4 (30 × 60)

ln[A] = -2.9957 - 1.206

ln[A] = -4.202

e^ln[A] = e^(-4.202)

A= 0.015 M

A pressure cooker contains 0.355 mole of air, which occupies a volume of 5.68 liters. The temperature inside the pressure cooker
sergejj [24]

Answer:

We will use ideal gas equation in this problem

PV = nRT

Where

P = pressure of gas or air = ?

V = volume of air = volume of pressure cooker = 5.68 L

T = temperature = 394 K

n = moles of air = 0.355

R = ideal gas equation = 0.0821 L atm / mol K

Putting values

Pressure = nRT / V = 0.355 X 0.0821 X 394 / 5.68 = 2.02 atm.
