The rate of reaction can be calculated by dividing the rate of consumption of a reactant by its stoichiometric coefficient in the balanced equation. In this case, the rate of reaction is 0.110 M/s
To determine the rate of reaction, we need to consider the stoichiometry of the reaction. From the balanced equation, we can see that 8 moles of A are consumed for every 7 moles of C produced.
Given that the rate of consumption of A is 0.881 M/s, we can convert this rate from moles per second to molar concentration per second by dividing by the stoichiometric coefficient of A. In this case, the stoichiometric coefficient of A is 8.
So, the rate of reaction would be:
(0.881 M/s) / 8 = 0.110 M/s
Therefore, the rate of reaction is 0.110 M/s.
