Thus, standard entropy change (ΔSo) is positive.Moreover, it is a combustion reaction and all the combustion reactions are generally exothermic, ie. Spontaneous and Nonspontaneous Reactions Entropy and Spontaneity. Thermodynamics Page 183 Q 6.19 Class 11 CBSE Chemistry. The type of questions that will be asked from NCERT Class 11 Chemistry Chapter 6 are displayed in the below provided NCERT Exemplar Class 11 Chemistry Chapter 6. Thus when a system goes from a more orderly to less orderly state, there is an increase in its randomness and hence entropy of the system increases. (II) Molecules at higher temperature have greater randomness at the same pressure. ... Entropy. Question 11. NCERT Solutions for Class 10 Maths. If randomness increases entropy increases. Hence, entropy decreases, i.e. Question 1. ∆ f H 0 = –286 kJ mol –1.
