Describe the structure and bonding in Graphite?

Arranged in different hexagonal layers, strong covalent bonds exist between carbon atoms, requiring lots of energy input in order to break. However, only weak inter-molecular forces exist between the differe...

In the production of anhydrous copper sulphate (a reversible reaction), the forward reaction is an endothermic reaction. Explain the effect of increasing the temperature on the production of anhydrous copper sulphate.

By increasing the temperature, the reactant particles gain more energy. This has a two-fold effect. Firstly, the reactant particles gain more kinetic energy, therefore they start to travel faster, resulting ...

Why does increasing temperature increase the rate of reaction?

Increasing temperature increases the rate of reaction for 2 reasons: the first (minor) reason is that particles have more kinetic energy with increasing temperature, so there are more collisions between reac...

How do I calculate bond enthalpy from a chemical reaction?

Example Q: See the reaction: CH 4 + Br 2 --> CH 3 Br + HBr, with bond energies as follows (in kJ/mol) :C-H = 412, Br-Br = 193,C-Br = x,H-Br = 366Overall energy = –51. Calculate x (bond energy of C-Br bond...
