A number of phenomenon, both physical, chemical and biological are concerned with redox reactions. These reactions find extensive use in pharmaceutical, industrial and agricultural areas.
Answer the following questions on the basis of above paragraph :
(a) What are redox reactions ?
(b) Give the application of redox reactions in photosynthesis.

Text Solution

Verified by Experts

(a) Redox reactions are those in which both oxidation and reduction takes place simultaneously.
(b) In photosynthesis, `CO_(2) and H_(2)O`, in the presence of light forms sugars and these reactions involves both oxidation as well as reduction of `CO_(2)` into sugar. Hence it follows redox reactions.

The integrated rate equations can be fitted with kinetic data to determine the order of a reaction. The integrated rate equations for zero, first and second order reactions are : Zero order : [Al =-kt+ [A]_0 First order : log [A] = -(kt)/2.303 + log [A]_0 Second order : 1/([A])=kt+1/[A]_0 These equations can also be used to calculate the halt life periods of different reactions, which give the time during which the concentration of a reactant is reduced to half of its initial concentration, i.e, at time t_(1//2), [A] = [A]_0//2 Answer the following (1 to 5) question : The decomposition of nitrogen pentoxide : 2N_2O_5(g) rarr 4NO_2(g) + O_2(g) is a first order reaction.

Read the given passage and answers following questions : A substance which alters the rate. of chemical reaction without itself undergoing any change in mass and chemical composition at the end' of reaction is called catalyst. It may be noted that a catalyst which increase the speed of a reaction are called positive catalyst and catalyst which decrease the speed of reaction are called negative catalyst. The promoters are substances that enhance activity of catalyst and poisons which decrease the activity of catalyst. The synthesis of proteins is governed by RNA. what is catalyst?

Read the given passage and answers following questions : Zeolites are alumino-silicates that are micro-porous in nature. Zeolites have a honeycomb like structure, which makes them shape-selective catalysts. They have an extended 3D-nelwork of silicates in which some silicon atoms are replaced by aluminium atoms, giving them an Al-O-Si framework. The reactions taking place in zeolites are very sensitive to the pores and cavity size of the zeolites. Zeolites are commonly used in the petrochemical industry. A catalytic reaction which depends upon the pore structure of the catalyst and on the size of the reactant and the product molecules is called shape-selective catalysis. For example, catalysis by zeolites is a shape selective catalysis. The pore size present in the zeolites ranges from 260-740 pm. Thus, molecules having a pore size more than this cannot enter the zeolite and undergo the reaction. In which chemical industry Zeolites used ?
