WebA catalyst is a substance that increases the rate of a chemical reaction without being consumed in the reaction. A catalyst works by providing a different pathway for the reaction, one that has a lower activation energy than the uncatalyzed pathway. WebJan 2, 2024 · For a general chemical reaction: aA + bB → cC + dD. the rate of the chemical reaction may be calculated as: Rate = k [A] a [B] b. Rearranging the terms, the rate constant is: rate constant (k) = Rate / ( [A]a[B]a) Here, k is the rate constant and [A] and [B] are the molar concentrations of the reactants A and B. fearless song download pagalworld https://roofkingsoflafayette.com
