Rate of Change in Chemical Reactions

What is the rate of change of SO2(g) in the given reaction?

The rate of change of CS2(g) is -0.012 M/s. What is the rate of change of SO2(g)?

Rate of Change Calculation:

Given that the rate of change of CS2(g) is -0.012 M/s and the rate of change of SO2(g) is 0.024 M/s in the reaction, find the rate of change of SO2(g).

Rate of change in a chemical reaction reflects the speed at which reactants are consumed or products are formed. In this case, we are examining the rates of change of CS2 and SO2 in a reaction involving the conversion of CS2 and oxygen into CO2 and SO2.

According to the stoichiometry of the balanced chemical equation for this reaction:

CS2(l) + 3O2(g) → CO2(g) + 2SO2(g)

It is clear that for every mole of CS2 consumed (-0.012 M/s), two moles of SO2 are produced. Therefore, the rate of change of SO2 can be calculated by doubling the rate of change of CS2.

Given the rate of change of CS2 is -0.012 M/s, the rate of change of SO2 would be:

2 * (-0.012 M/s) = -0.024 M/s

Hence, the rate of change of SO2 in the given reaction is -0.024 M/s. This is a result of the stoichiometric relationship between CS2 and SO2 in the balanced chemical equation.

This calculation demonstrates the interplay between reactants and products in a chemical reaction and how their rates of change are interconnected based on the reaction stoichiometry.
