At room temperature (20°C) milk turns sour in about 64 h. In a refrigerator at 3°C milk can stored three times as long before it sours. How long should it take milk to sour at 40°C.

Question

Arun · Answer

Dear student, Given K (293)/K(276) = 3 T2 = 293 K, T1 = 276 K 2.303 log (K2/K1) = E a (T2 -T1)/R* (T1)(T2) On solving E a = 10.454 Kcal Also 2.303 log(K3/K2) = E a (T3-T2)/2* (T3)(T2) Where T3 = 313 K Now on solving K3 = 3.12 K3/K2 = t2/t3 Where t2 = 64 Hr., We have to find t3 Now t3 = 64*1/3.12 = 20.5 hr Regards Arun (askIITians forum expert)
