In a chemical equilibrium, the position of the equilibrium will always move to oppose any change in temperature, pressure or concentration of reactants/products. For example, if temperature is increased, ...

Imagine the reaction A + B <-> C+D where the forward reaction is exothermic. If we increase the temperature of the surroundings, the equilibrium is going to shift to the direction that reduces the t...

Strong covalent bonds present between atoms in silicon dioxide. VDW (Van Der Waals) between molecules in sulphur trioxide. Covalent bonds are stronger than VDW. Covalent bonds require more energy to be ov...

There are three properties to consider when looking at ionisation energy:Atomic chargeAtomic radiusElectron shieldingGoing along a period, the atomic charge increases as there are more protons in the nucl...
