2. Based on this question, decide for each of its positive or negative? Use the observations about each chemical reaction in the table below todecide the sign (positive or negative) of the reaction enthalpy ▲ andreaction entropy as.Note: if you have not been given enough information to decide a sign,select the "unknown" option.reactionABCobservationsThis reaction is spontaneous only above-9. °C but proceeds at a faster rate above189. °C.This reaction is always spontaneous, butproceeds faster at temperatures above136. °C.This reaction is exothermic and proceedsslower at temperatures below 37. °C.AH isAS isconclusionsAH isAS isAH isAS is(pick one)(pick one)(pick one)(pick one)(pick one)(pick one)

Given:Reaction A:Spontaneous above Proceeds at a faster rate above 189oC.Reaction B:Always spontaneousProceeds faster at a temperature above 136oCReaction C:Exothermic reaction Proceeds slower at temperatures below 37oCDetermine for these three reactions.The change in enthalpy, or (), is the amount of heat that is absorbed or released during a process, like a chemical reaction.(): The variation in entropy, a gauge of a system's disorder or randomness that represents the extent of energy dispersion.The spontaneity of a reaction is described by the sign of its change in free energy. If the change in the free energy of a reaction is negative then the reaction is spontaneous if the change in the free energy of a reaction is positive then the reaction will be nonspontaneous. The change in Gibbs free energy of a reaction will depend on the enthalpy and the entropy of the reaction as follows: (A) Reaction is spontaneous only above but proceeds at a faster rate above . It means the reaction is spontaneous at high temperatures only. Hence, the sign of should be positive and the sign of should be positive for the given reaction. (B) For a spontaneous reaction, should be negative.Reaction is always spontaneous it means (C) The reaction proceeds slower at a temperature below it means reaction is spontaneous below but the rate of reaction decreases due to a decrease in temperature and reaction also proceeds at a temperature above so, the reaction is spontaneous at all temperatures. (at all temperature)Therefore, (A) (B) (C)
