Rate of reaction is based on collision frequency: chemicals react when molecules come into contact with each other with enough energy to react. If you want to increase the rate of reaction, you need to fi...

Carbon is in group 4 of the periodic table therefore has 4 electrons in its outer shell which are available for bonding. Each carbon atom in graphite forms 3 covalent bonds with another carbon atom within...

This is the weakest intermolecular force. It is formed by the uneven distribution of electrons in a molecule which induces a dipole in the molecule (meaning a delta positive and delta negative charge form...

Increasing the temperature of an endothermic reaction would favour the forward reaction, thereby increasing the concentration of the products compared to reactants, which in hand increases the value of Kc...

Q. A sample of strontium has a relative atomic mass of 87.7 and consists of three isotopes, ⁸⁶Sr, ⁸⁷Sr and ⁸⁸Sr. In this sample, the ratio of abundances o...
