in a chemical equilibrium if the reaction time tends to infinity, the concentration of reagents tends to zero since they will be totally converted into products.
¿True or false?
Homework Answers
False. As the chemical equilibrium is achieved the rate of formation of products is equal to the rate of formation of the rectants . i.e the rate of forward reaction is equal to the rate of backward reaction. It doesnt mean that the whole reagents will be converted o the products and their conecentration will be zero. The concentration of reactants and the products remains constant when the chemical equilibrium is achieved.
