Question

Which statement is correct for the reaction below?

4X + Z yields 2R + 2S

The rate of formation of R is one-half the rate of the disappearance of Z.
The rate of disappearance of Z is one-fourth of the rate of disappearance of X.
The rate of formation of R is double the rate of formation of S.
The rate of formation of S is double the rate of disappearance of X.

Answer 1

@Abhisar ?

Answer 2

What do you think it should be ?

Answer 3

umm. The rate of formation of R is one-half the rate of the disappearance of Z.
cause ...4 yields 0
1 yields 0

Answer 4

The rate of formation of R is double the disappearance of Z honey :(
Z:R
1:2

Answer 5

oh. but i am kinda confused?

Answer 6

Ratio of X:Z = ?

Answer 7

1:0
??

Answer 8

:O

Answer 9

`4X + Z` yields 2R + 2S. So what is X:Z ?

Answer 10

Each mole of Z reacts with 4 moles of X

Answer 11

So,
The rate of disappearance of Z is one-fourth of the rate of disappearance of X or rate of disappearance of X is four times the rate of disappearance of Z

Answer 12

Getting it ?

Answer 13

4X + Z yields 2R + 2S. So what is X:Z ?
okay i am noob to this could you please explain how to find the ratio to this?

Answer 14

When there is no coefficient, we take it as 1

Answer 15

oohhh yes okay!

Answer 16

Suppose,
5A + 7B --> 8C + 3D. Then what is the ratio B:D ?

Answer 17

7: 3
??

Answer 18

\(\huge\checkmark\)

Answer 19

yay! so them how do i get the answer

Answer 20

Check each option if it is true or false.

Answer 22

oh okay
option one: R:Z which is 2:1

Answer 23

This means that rate of formation of R is double the rate of disappearance of Z because only 1 mole of Z is required for the formation of 2 moles of R [Z:R=1:2]

Answer 24

So the statement A is FALSE

Answer 25

oh and it is wrong 'cause R is twice as big
option two 4:1 YAS
option 3: 2:2 nope
option 4: 2:4 nope
so it is option 2?

Answer 26

What is YAS ;p

Answer 27

B \(\huge\checkmark\)

Answer 28

idk people here say yas for fun but means yes :D

Answer 29

R.I.P YES

Answer 30

:D

Answer 31
