Question

The value of ionic product kw are 0.64x1024 at 18 °C, 1x10-14 at 25 °c. From this may be derived that

A. Endothermic process
B. Exothermic process
C. Vaporization process
D. Change of H2O into 02 and H2​

Answer 1

Answer:

Ur values are not clear

1.If ionic product at 18>25 C then it must be exothermic

(For exothermic reaction ,temp is inversely proportional to reaction)

2.If ionic product at 25>18C then it must be endothermic

(For endothermic reaction ,temp is directly proportional to reaction)

Answer 2

Explanation:

comparing both

(0.64x10^24 & 1x10-14) kw

there fore the ionic product of 18 ° C is greater

hence required ans is.

B. exothermic
