Given that Kp = 1.5 x 10-4 for the reaction 2 CO(g) <=> C(graphite) + CO2(g), what is the partial pressure of CO2(g) at equilibrium if initially 4.00 atm of CO(g) is in contact with graphite?
C2H4 is emitted by fruits and is responsible for their ripening. Explain why a bunch of bananas ripen faster when placed in a paper bag.
Also, mention the design process of this category of battries.
.8 grams of sulfur is combusted to form SO2. All of the heat evolved is used to raise the temperature of 100.0grams of water by 17.8 K. Specific heat of water is 4.813J/gK. Compute the heat of combustion of 1 mol of sulfur.
