Question

HCOOH () HCOOOH (s) e, what is the standard molar entropy of HCOOH (s)? So HCOOH()-109 1 J/molK f. Is the magnitude of So for HCOOH (s) in agreement with the magnitude of So for HCOOH 0)? Explain IV. Essay: Answer the following questions. Be sure thoughts are in logical, coherent order. Use complete sentences and not the bullet method a. Explain the significance of negative signs for enthalpy, entropy and Gibb's free energy b. In a given reaction all the above signs were negative. Would the reactants or products be in highest amount? Explain. Under what conditions would make this reaction equal to a positive (delta)G? c.

Explanation / Answer

a). negative sign of enthalpy shows reaction is exothermic

negative sign of entropy shows decrease in disorder or ordered system

negative sign of G ie is free energy shows the reaction is spontaneous.

b).Since delta G is negative the reaction is spontaneous favouring product formation further delta H and delta S is negative requirement of delta G to be negative can be approached by greater negative value of delta H inorder to overcome effect of positive factor Put forward by TDeltaG.

c).In order to achieve positive delta G delta H should be positive and delta s should be negative.
