The decomposition of NH 3 on platinum surface is zero order reaction. Sol: As the concentration in the rate law equation is given gheory terms of pressure. Mention the factors which affect the rate of a chemical reaction. Sol: The rates of chemical reactions are influenced by a number of factors. These Solutions Of Ch 10 Maths Class 10 Theory are : i C oncentration of reactants. The rate of a chemical reaction is proportional to the concentration of the reacting species taking part in the reaction.
It is maximum to start with and slowly decreases since the concentration of the reacting species decreases accordingly. In case of reversible chemical reactions, thory rate of chemical reaction can be studied separately for both the forward and backward reactions. In case of gaseous reactions, the increase in pressure increases the reaction rate. In general, the increase in temperature increases the reaction rate Solutions Of Ch 10 Maths Class 10 Theory there are a few exceptions as.
Actually, the energy of the reactant species increases with the increase in temperature and so will be number of collisions. Please note that the effect of temperature is quite independent of the concentration of the reactant species.
In many chemical reactions, the reaction rate can be enhanced by certain foreign substances called catalysts. These are actually not consumed in the reactions and also donot undergo any change in chemical characteristics.
However, their physical states such as colour, particle size. Certain catalysts may have adverse effect as well as the reaction rate.
They result in decreasing the reaction rate instead of increasing it. These are called negative catalysts or inhibitors. The nature of the reacting Solutions Of Ch 10 Maths Class 10 Theory solutions of ch 10 maths class 10 theory may also the influence the reaction rate. For Solutions Of Ch 10 Maths Class 10 Theory example, combustion of nitric oxide NO is faster as compared to that of carbon monoxide CO. Increase in surface area provides more opportunity for the reactants to come in contact or collide resulting in increased reaction rate.
For example, in laboratory. We solutions of 10 Of 10 Theory Ch Solutions Class Maths Solutions Of Ch 10 Maths Class 10 Theory ch 10 maths class 10 theory often prefer granulated zinc lump of the metal while preparing hydrogen gas on reacting with dilute hydrochloric acid or dilute sulphuric acid. Actually, granulated Theory 10 Solutions 10 Of Class Ch Maths Solutions Of Ch 10 Maths Class 10 Theory zinc has greater surface area available for the attack by the acid than lump of zinc.
Therefore, it reacts at a faster rate. Many chemical reactions known as photochemical reactions are carried in the presence of sun light. For example, In these reactions, the photons of light are the source of energy which helps in breaking the bonds in the reacting molecules so that may react and form molecules of products.
