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. WebFeb 9, 2009 · If possible, start with an element found in one compound on each side of the equation. Change the coefficients (the numbers in front of the compound or molecule) so that the number of atoms of the element is the same on each side of the equation.
