The Lorentz Force
The Lorentz force is the force experienced by a moving charged particle in an electric and magnetic field. The magnetic component is:F=qvBwhere F is the force (in newtons, N), q is the electric charge (in coulombs, C), v is the velocity of the charged particle (in m·s−1) and B is the magnetic fie…

EQUILIBRIUM TASKS
Exercise 1: Equilibrium Problem 1: The following reaction has reached equilibrium in a closed container: C(s)+H2O(g) ⇌ CO(g)+H2(g) ΔH> 0 The pressure of the system is then decreased. How will the concentration of the H2 (g) and the value of Kc be affected when the new equilibrium is established? Assume that the temperature of the system remains unchanged. . Table 2 Hydrogen concentration Kc…

Charles Law
The volume of a fixed mass of gas is inversely proportional to its pressure at constant temperature. The volume of a fixed mass of gas is directly proportional to its temperature at constant pressure. v ∝ t v = k t v = k t As you can see, the line, when extended backwards crosses…

Boyle’s law
The volume of a fixed mass of gas is inversely proportional to its pressure at constant temperature. p ∝ 1 / v p = k 1 /v pv = k If the pressure and volume of a fixed mass of gas take the values of p1 v1and p2 v2 respectively, p1 v1 = p2 v2…
