In chemistry, the rate equation (also known as the rate law or empirical differential rate equation) is an empirical differential mathematical expression for the reaction rate of a given reaction in terms of concentrations of chemical species and constant parameters (normally rate coefficients and partial orders of reaction) only.

The Gakken EX-150 set up for experiment #108. The Gakken EX-System is a series of educational electronics kits produced by Gakken in the late 1970s. The kits use denshi blocks (also known as electronic blocks) to allow electronics experiments to be performed easily and safely.
Under these conditions, the system can be described by a "one-plus" rate law where the numerator consists of all rate constants and species required to go from starting material to product, and the denominator consists of a sum of terms describing each of the states in which the catalyst exists (and 1 corresponds to the free catalyst). [17]
A simple example of such a system is the case of a bathtub with the tap running but with the drain unplugged: after a certain time, the water flows in and out at the same rate, so the water level (the state variable Volume) stabilizes and the system is in a steady state. The steady state concept is different from chemical equilibrium.
Law enforcement conduct an investigation in connection with the New Orleans terrorist attack near the intersection of Hugh Road and Crescent Peak Drive in Houston, Texas on January 1, 2025.
Meanwhile, the federal minimum wage of $7.25 an hour hasn't budged since 2009, and it remains the law in 20 states. Since then time, that base rate has lost 30% of its purchasing power due to ...
Apple agreed to pay $95 million in cash to settle a proposed class action lawsuit claiming that its voice-activated Siri assistant violated users' privacy. A preliminary settlement was filed on ...
For Faraday's first law, M, F, v are constants; thus, the larger the value of Q, the larger m will be. For Faraday's second law, Q, F, v are constants; thus, the larger the value of (equivalent weight), the larger m will be. In the simple case of constant-current electrolysis, Q = It, leading to
