Solution: In a particular experiment, it was found that when O2(g) and CO(g) were mixed and allowed to react according to the equation:2CO(g) + O2(g) ⇌ 2CO2(g) the O2 concentration had decreased by 0.078 mol L-

Problem

In a particular experiment, it was found that when O2(g) and CO(g) were mixed and allowed to react according to the equation:

2CO(g) + O2(g) ⇌ 2CO2(g) 

the O2 concentration had decreased by 0.078 mol L-1 when the reaction reached equilibrium. How had the concentrations of CO and CO2 changed?

The number of significant digits is set to 2; the tolerance is +/-1 in the 2nd significant digit.
