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 diff...

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, resulti...
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 r...
Example Q: See the reaction: CH4 + Br2 --> CH3Br + HBr, with bond energies as follows (in kJ/mol) :C-H = 412, Br-Br = 193,C-Br = x,H-Br = 366Overall energy = –51. Calcu...
