At room temperature, the equilibrium constant for the reaction P + Q 
R + S was calculated to be 4.32. At 425°C the equilibrium constant became 1.24 × 10 –2 . This indicates that the reaction
A
is exothermic
B
is endothermic
C
is difficult to predict
D
no relation between 
H and K
H and K
Text Solution
Verified by ExpertsThe correct answer is:
A
At room temperature, K = 4.32 and at 425°C, equilibrium constant become 1.24 × 10 –4 i.e. it is decreases with increase in temperature. So, it is exothermic reaction.
