Answer: A) This reaction will be spontaneous only at high temperatures
Explanation:
= +ve, reaction is non spontaneous
= -ve, reaction is spontaneous
= 0, reaction is in equilibrium
Using Gibbs Helmholtz equation:
Given : 
Thus the value of is negative and spontaneous when temperature is high.
Answer:
The attractive force between them decreases
Explanation:
This is because they become localised.
Density = mass/volume = 800/200 =4 g/cm^3
DR is the correct answer
hope this helps
1 Kj ------------- 1000 J
?? --------------- 10 J
10 x 1 / 1000 => 0.01 Kj
