If for a reaction `Delta H=50kJ/mol`,`Delta S=50J/K -mol` then `Delta G` at 500K will be (A) 25kJ/mol (B) 5000kJ/mol (c) 0.5kJ/mol (D) 10000kJ/mol

For a reaction DeltaH = -158.73KJ//mol, DeltaS= -58.1J//K , T= 298K then value of DeltaG (in KJ) is

For a reaction DeltaG^@ = -51.4 KJ/mol and Delta H^@ = 49.4 KJ/mol at 300K, then value of DeltaS^@ in J/K is

ArarrB, DeltaH= -10 KJ mol^(-1), E_(a(f))=50 KJ mol^(-1) , then E_(a) of BrarrA will be

For a reaction DeltaH=+29kJ" "mol^(-1),DeltaS=-35KJ^(-1)" "mol^(-1) at what temperature, the reaction will be spontaneous?

Calculate DeltaG_(reaction) ("kJ"//"mol") for the given reaction at 300 K A_(2)(g)+B_(2)(g)hArr2Ab(g) and at particle pressure of 10^(-2) bar and 10^(-4) Given : Delta H_(f)^(@) AB =180 kJ//mol," "DeltaH_(f)^(@) A_(2)=60 kJ//mol Delta H_(f)^(@) B_(2) = 29.5 kJ//mol," "DeltaS_(f)^(@) AB=210 J//K-mol Delta S_(f)^(@) A_(2) = 190 kJ//mol," "DeltaS_(f)^(@) B_(2)=205 J//K-mol Use : 2.303 Rxx300=5750 "J"//"mole"

Following are the values of E_(a) and Delta H for three reactions carried out at the same temperature : I: E_(a) =20 kJ mol^(-1), Delta H =-60 kJ mol^(-1) II: E_(a) =10 kJ mol^(-1), Delta H =-20 kJ mol^(-1) III: E_(a) =40 kJ mol^(-1), Delta H=+15 kJ mol^(-1) If all the three reaction have same frequency factor then fastest and slowest reactions are :

For a reaction, DeltaH=10000" kJ "mol^(-1) and DeltaS=25" kJ "k^(-1)mol^(-1) . The minimum temperature, above which the reaction would be spontaneous is
