Consider the following reaction: C a C O 3 ( s ) ? C a O ( s ) + C O 2 ( g ) . E

Question

Consider the following reaction:
CaCO3(s)?CaO(s)+CO2(g).
Estimate ?G? for this reaction at each of the following temperatures. (Assume that ?H? and ?S? do not change too much within the given temperature range.)'

a. 1035K

b. 1035K

c. 143cc. 1435K

Calculate ?G? at 298 K for the following reactions.

a. NH3(g)+HBr(g)?NH4Br(s)

and plz explain how to know delta H and delta S?G?H and ??

Calculate ?G? at 298 K for the following reactions.Calculate ?G? at 298 K for the following reactions.NH3(g)+HBr(g)?NH4Br(s)

Explanation / Answer

delta G = -RT ln(Kg)

Kg is equilibrium constant due to gaseous CO2 ...

deltaGo =0 at equilibrium.
