Question

Match the following catalysts with the process in which they are used:

(a) Vanadium Pentoxide (b) Amylase (c) Iron (d) Phosphoric acid

(i) Biological processes (ii) Manufacture of Sulphuric acid (iii) Manufacture of Ammonia (iv) Reduce the decomposition of Hydrogen Peroxide

• A. (a) - (i), (b)- (ii), (c)- (iv) and d- (iii)
• B. (a) - (ii), (b)- (i), (c)- (iii) and d- (iv)
• C. (a) - (i), (b)- (ii), (c)- (iii) and d- (iv)
• D. (a) - (iv), (b)- (iii), (c)- (ii) and d- (i)

Answer 1

The correct option is B

(a) - (ii), (b)- (i), (c)- (iii) and d- (iv)

A catalyst is a substance which alters the rate of the chemical reaction without itself undergoing any chemical change. There are two types of catalysts:

(a) Positive catalyst

(b) Negative catalyst

Following are few catalysts and the process in which they are used:

(i) Vanadium Pentoxide- Used in the manufacture of sulphuric acid

(ii) Amylase- Used in biological processes

(iii) Iron- Used in the manufacture of ammonia

(iv) Phosphoric acid- Used to reduce the decomposition of Hydrogen Peroxide
