Given the following reaction at equilibrium,  A + 3B  ↔  2C + 2D    ΔH = 20.91 kJ/mol The amount of C in the system can be increased by:

A 0.2 M solution of formic acid has a pH of 5.0.  What is its Ka value?

Butane burns in oxygen according to the following balanced equation: C4H10 + 13/2 O2  ↔  4CO2 + 5H2O If the butane is consumed at the rate of 1.50 L/s, the oxygen is consumed at the rate of:

C2H6 –> C2H2 + 2H2    ΔH = 319.92 kJ/mol. An alternate way to write this equation is:
