| real time |
An operation within a larger dynamic system is called a real-time operation if the combined reaction- and operation-time of a task is shorter than the maximum delay that is allowed, in view of circumstances outside the operation. The task must also occur before the system to be controlled becomes unstable. A real-time operation is not necessarily fast, as slow systems can allow slow real-time operations. This applies for all types of dynamically changing systems. ...

| reaction quotient |
where A, B, C, and D are four chemical species involved in this reaction and k, m, n, and p are the coefficients. And the expression for the reaction quotient is: where the square brackets denote the concentrations of the various chemical species involved in the reaction in molarity, and the ' i ' denotes the instantaneous concentration at a certain period of time. This is crucial in understanding the idea of the Reaction Quotient. ...
