Sodium carbonate can be made by heating sodium bicarbonate:
2NaHCO3(s) ¨ Na2CO3(s) + CO2(g) + H2O(g)
Given that ƒ¢H‹ = 128.9 kJ/mol and ƒ¢G‹ = 33.1 kJ/mol at 25‹C, above what minimum temperature will the reaction become spontaneous under standard state conditions? Answer in celsius

HW Entropy Question 
bobpursley,
33.1kj/mol =128.9kj/molT(dS) Put in T (273+25) and find dS.
then,
0=128.9Kj/molT ds use your found dS, then solve for T. Convert to Celcius
