What effect does temperature change have on an equilibrium reaction?

First, it depends on whether the forward reaction is exothermic or endothermic. Lets use the formation of ammonia as an example: N2 + 3H2 <-> 2NH3. The forward reaction is exothermic, so it releases...

Why is the molecule CH4 tetrahedral whereas NH3 is not?

By the VSEPR (Valence shell electron pairs repulsions) theory, even though there are four electron pairs on C and N, the presence of a lone pair of electrons on N increases the repulsions, meaning that th...
