For a reaction, A⇌P , the plots of [A]and [P] with time at temperatures T1 and T2 are given below.
If T2>T1 , the correct statement(s) is (are)
(Assume ∆H⊝ and ∆S⊝ are independent of temperature and ratio of lnK at T1 to lnK at T2 is greater than T2/T1 . Here H, S , G and K are enthalpy, entropy, Gibbs energy and equilibrium constant, respectively.)
A⇌P
Given T2>T1
lnK1lnK2>T2T1
⇒ T1lnk1>T2lnk2
⇒ -∆G01>-∆G02
⇒ (-∆H0+T1∆S0)>(-∆H0+T2∆So)
⇒ T1∆S0>T2∆S0
⇒ ∆So<0
At T2 temperature concentration of product is decreases that shows reaction is exothermic.
