How are `DeltaH and DeltaE` are related for a gaseous equilibrium reaction ? What is `(DeltaH - DeltaE)` for `CaCO_(3(s)) to CaO_((s)) + CO_(2(g))`? 

When charcoal burns in air signs of DeltaH and DeltaS "are " 2C_((s)) + O_(2(g)) rarr 2CO_((g))

For the reaction CaCO_(3(s)) hArr CaO_((s))+CO_(2(g))k_p is equal to

Write the equilibrium constant expression for the following equilibria: CaCO_3(s) hArr CaO(s) + CO_2(g)

sort out the homogeneous and netrogeneous equilibrium from the following CaCO_3(s) hArr Cao (s) + CO_2(g)

The following are some state ments regarding dissociation of lime stone according to the equation CaCO_(3(s)) hArr CaO_((s)) + CO_(2(g)) : Delta H = 110 kJ. The reaction is carried in a closed vessel. A) The pressure of CO_(2) increases when temperature is inereased. B) The pressure of CO_(2) inereases when temperature is deereased C) The pressure of CO_(2) increases when amount of CaCO_(3) is decreased. The incorrect statements are .

State the second law of thermodynamics. Predict the sign of DeltaS in the following change at constant temperature and pressure. Give reason in support of your answer. CaCO_3(s) to CaO(s) + CO_2(g)

In each of the following, total pressure set - up at equilibrium is assumed to be equal and is P atm with equilibrium constants K_(p) given : I: CaCO_(3)(s)hArr CaO(s)+CO_(2)(g),K_(1) II : NH_(4)HS(s)hArr NH_(3)(g)+H_(2)S(g),K_(2) III : NH_(2)CO_(2)NH_(4)(s)hArr 2NH_(3)(g) +CO_(2)(g),K_(3) In the increasing order :

What is the minimum mass of CaCO_3(s) , below which it decomposes completely, required to establish equilibrium in a 6.50 litre container for the reaction : CaCO_3(s)hArr CaO(s)+CO_2(g), K_c=0.05

Calculate the pressure of CO_(2) gas at 700 K in the heterogenous equilibrium reaction CaCO_(3)(s) hArr CaO(s)+CO_(2)(g), if DeltaG^(ɵ) for this reaction is 130.2 kJ mol^(-1) .

A sample of CaCO_(3)(s) is introduced into a sealed container of volume 0.654 L and heated to 1000 K until equilibrium is reached. The equilibrium constant for the reaction CaCO_(3)(s)hArrCaO(s)+CO_(2)(g), is 3.9xx10^(-2) atm at this temperature. Calculate the mass of CaO present at equilibrium.
