Concept introduction:
Rate of a reaction is the speed at which the reactant changes into product. There are many factors which affects rate of a reaction, such as, nature of reactant, concentration of reactant, surface area of reactant, temperature etc.

Answer to Problem 17SSC
The rate of reaction quadruples, if temperature of 20 K is increased.
Explanation of Solution
When the temperature increases, the average kinetic energy of the particles of the substance also increases. So, reacting particles undergoes collision more frequently in higher temperature as compared to lower temperature. So, increase of temperature increases rate of a reaction. Given that, on increasing temperature of 10 K doubles rate of reaction, similarly increasing 20 K temperatures quadruples the reaction rate.
Increasing temperature leads to increase of rate of reaction.

In essence, the molecule reacts with itself. Draw the structure of the products formed in this manner using the reactants below. If two functional groups interact with one another on the same molecule, this is called an “intramolecular" (within one) rather than "intermolecular" (between two or more) attack.
