For a sequential reaction :
A rightarrow B + C
2B rightarrow C + 2D
If % yeild of (i) and (ii) reactions are 90% and 80% respectively, then the overall % yield is expected to be:

For the sequential reactions: 2A overset(80%)to 3B + C 2B overset(50%)to 5D + E Moles of A needed for the formation of 1.5 moles of D is:

In the measurement of a physical quantity x =(A sqrt(B))/(C^(2)) .The percentage error in measurement of the quantities A,B,C are 1%,2% and 2% respectively.Then the maximum possible percentage error in x is % .

For the reactions : A overset (rightarrow) (leftarrow) B , K_C = 1 B overset (rightarrow) (leftarrow) C , K_C =2 C overset (rightarrow) (leftarrow) D , K_C for the reaction A overset (rightarrow) (leftarrow) D is—

Two numbers A and B are respectively 80% and 50% more than the third number C. What is the ratio of A and B?

If 90% of A = 30% of B and B = 2x% of A, then the value of x is

Percentage yield, series and sequential reactions

A zero order reaction \(A\rightarrow B\) .At the end of the of 1h,' A is 75 % reacted. How much of it will be left unreacted at the end of 2 h?

If X=(a^(3)b^(2))/(sqrt(c)d) and percentage errors in a, b, c and d are 1%, 2%, 4% and 4% respectively, then the error in X will be

If X=(a^(3)b^(2))/(sqrt(c)d) and percentage errors in a, b, c and d are 1%, 2%, 4% and 4% respectively, then the error in X will be
