Calculate deltaGrxn for the reaction below at 25C

2Ca(s) + O2(g) = 2CaO(s)

given:

deltaH'rxn= -1270.2 kJ

deltaS'rxn= -211.9J/K

a) -1058.3 kj b) -1207.0 kj c) -1333.4 d) -1482.1 kj

Given that

C(s) + O2(g) = CO2(g) DeltaG'= -394.4 kj

CO(g) + 1/2O2(g) = CO2(g) DeltaG'= -257.2kj

Calculate deltaG' for the following reaction.

2C(s) + O2(g) = 2CO(g)

a) -651.6 kJ b) -274.4 kJ c) -137.2 kJ d) +137.2 kJ e) +274.4 kJ

For a chemical system deltaS' and deltaS are equal when

a) the system is in equilibrium.

b) the reactants and products are in standard state conditions.

c) deltaG' and delta G are both positive.

d) the reactants are elements.

e) the reactants and products are in the gas phase.

A) delta G = delta H - ( T x delta S)

-1270.2kJ - ( 298 x (-211.9))

= -1207 kJ

B) 2 x( C(s) + O2(g) -> CO2(g)) + 2 x ( (co2--> 1/2O2+CO))

=== 2C(s) + O2(g) = 2CO(g)

(2 x (gibbs energy 1)) + ( 2 x ( - G of eq 2))

= - 274.4kJ

C) a
