🤓 Based on our data, we think this question is relevant for Professor Hoff's class at UM.
Sodium carbonate can be made by heating sodium bicarbonate:
2 NaHCO3 (s) → Na2CO3(s) + CO2(g) + H2O(g)
Given that standard enthalpy of reaction is 128.9 kJ and the standard Gibbs energy of reaction is 33.1 kJ at 25oC, above what temperature is the reaction become spontaneous? Assume that the enthalpy and entropy of reaction do not depend on temperature.
a) 0.4 K
b) 3.9 K
c) 321 K
d) 401 K
e) 525 K
