Question
Questions 7-9 refer to the following information.
At 27°C, five identical rigid 2.0 L vessels are filled with N2(g) and sealed. Four of the five vessels also contain a 0.050 mol sample of NaHCO3(s), NaBr(s), Cu(s), or I2(s), as shown in the diagram. [VISUAL]
At 127°C, the pressure in vessel 1 is found to be higher than that in vessel 2. Which of the following reactions best accounts for the observation?
A.
NaHCO3(s) → Na(s) + HCO3(s)
B.
NaHCO3(s) → NaH(s) + CO3(g)
C.✓ Correct
2 NaHCO3(s) → Na2CO3(s) + H2O(g) + CO2(g)
D.
2 NaHCO3(s) + N2(g) → 2 NaNO3(s) + C(s) + H2(g)
