Question

The initial rate of zero order reaction of a gaseous reaction,
Ag- 2B(g),
is 10- M min-. If initial concentration of A is 2M. Then what would be rate of reaction after
120 seconds.​

Answer 1

Answer:

Let the two prime numbers be 3 and 5.

 

 

Multiples of 3 and 5 are as follows

3   ...  3, 6, 9, 12, 15, 18,....

5   ...  5, 10, 15, 20, ....

 

LCM(3, 5) = 15

 

Since 3 and 5 are prime numbers.

HCF(3, 5) = 1

 

 

LCM(3, 5) ×  HCF(3, 5) = 15 × 1 = 15   ... (ii)

3 × 5 = 15   ...(iii)

From (ii) and (iii), we can say that  

 

The product of any two prime number is equal to the product of their HCF and LCM.

Answer 2

Answer

Explanation:

As we know for zero order reaction,

k= 10 ka power -3 M/min

now,

k=10/60 ka power -3 M/SEC

rate= final amount - initial amount /time

     =  2 multiple 10*-3/ 120

rate      = 1.67 × 10*-5 M/sec answer
