Give balanced equations, wherever possible, or where this is not possible, explain the following by means of examples: i) A reaction which gives out heat. ii) A reaction which takes place with the help of sunlight. iii) A reaction which is brought about by electric current. iv) A reversible reactions

At time t = 0 (before the reaction starts), the reaction has 100 concentration units of compounds A and B and zero units of compound D. We now allow the reaction to proceed and observe the individual concentrations of the three compounds over time (t=1, 5, 10, 15, 20, 25, 30, 35, and 40 time units) When a reaction causes the rupture of these bonds, it causes the energy in them to be released, generating an exothermic reaction. Examples of exothermic chemical reactions . Exothermic reactions are always accompanied by an increase in temperature, and mostly by sparks, flames, smoke, or some sound (Helmenstine, 2016) Background. The kinetic isotope effect is considered to be one of the most essential and sensitive tools for the study of reaction mechanisms, the knowledge of which allows the improvement of the desirable qualities of the corresponding reactions.For example, kinetic isotope effects can be used to reveal whether a nucleophilic substitution reaction follows a unimolecular (S N 1) or bimolecular. Real-Life Examples of Reversible Process. At normal pressure and at 273 K temperature if some amount of ice absorbs heat for transformation into the water and equal amount of water rejects the same amount of heat in order to be transformed into an ace, then it is a reversible process. Some examples of reversible prose are given below Reversible reactions are ones which occur in both directions at the same time.. We represent them using a double arrow: reactants products. If a reversible reaction is exothermic (gives out energy) in one direction it is endothermic (takes in energy) in the other direction.. When a reversible reaction takes place in a closed system an equilibrium will be reached

In this reaction, the more electronegative chlorine displaces iodine from its salt, potassium iodide. Here, zinc is oxidised to +2 state from zero state, and hydrogen is reduced to zero state from +1 state The more stable product, i.e. product B, is known as the thermodynamic product of the reaction. Examples 2-Methylcyclohexanone. When 2-methylcyclohexanone is an asymmetric ketone. When it is exposed to basic conditions, it can undergo enolate formation on either side of the molecule to produce either kinetic product (A) or thermodynamic product.
