## Ruchi. 2 years ago Q. the graph relates In K vs 1/T for a reaction .the reaction must be :

1. Ruchi.

|dw:1354201232478:dw| A) exothermic B) endothermic

2. Ruchi.

which option is correct?

3. Ruchi.

4. Ruchi.

can u hlp me out .plzzz

5. ajprincess

i am really sorry. I have no idea

6. Ruchi.

can u suggest any one on os to hlp me @ajprincess

7. ajprincess

I am nt sure. i rarely visit chemistry group. So have no idea. Am really sorry.

listen from the graph we find out the how K depends on temperature now we know that on increasing temp favourable for endothermic but here K i increasing on decreasing temp means it exothermic

10. heena

might u read some law like on increasing temp exothermic show backward reaction while endothermic show forward reaction

11. Ruchi.

temp is also increasing

12. heena

no its not see 1/T

13. Ruchi.

i'm nt understanding the graph ?

14. heena

do u know wat is k?

15. Ruchi.

euilibrium constant?

16. heena

yes and will u give me the formula of kc

17. heena

that is kc=concn of product/concn of react

18. heena

ok now here in graph K is increasing on increasing the value of 1/T means temp i decreasing and on deacresing temp and K also increasing then it must be a exothermic process

19. Ruchi.

in starting its temp. is 1.5 ,2,2.5 so its increasing

20. heena

dear its not T u are provided 1/T

21. Ruchi.

wat is 1/t

22. heena

1/T means if the values are given are in increasing order den T is decreasing but if its value of T given in increassing order then T i increasing

23. Ruchi.

decreasing then increasing

24. heena

see whther they written T or 1/T or ask ur teach dey will explain u the difference abu T and 1/T

25. Ruchi.

okay .

26. Ruchi.

wait.

27. Ruchi.

i hav understood it wait i'm posting 2nd question.
