Post by: Whelan on May 6, 2015
When baking soda is heated it decomposes according to the following reaction:

2 NaHCO3(s) <-- --> Na2CO3(s) + H2O(g) + CO2(g)

If sufficient baking soda is placed in a container and heated to 90°C, the total pressure of the gases is 0.5451 atm. What is the value of Kp at that temperature?
A) 0.07428
B) 0.2973
C) 0.4228
D) 1.091
