WebThe Python interpreter treats chained constraints in such a way that CVXPY cannot capture them. CVXPY will raise an exception if you write a chained constraint. Parameters¶ Parameters are symbolic representations of constants. The purpose of parameters is to change the value of a constant in a problem without reconstructing the entire problem. WebSince at equilibrium the rates of the forward and reverse reactions are the same, one single representation cannot capture the dynamic nature of this process. Multiple representations of the reaction before and after equilibrium would be needed to show that the concentrations of the ions have remained constant over time.
