WebSubstituting in the reaction-rate expression, r = k (T )c A, and using the number of moles of A, n A = c A V R yields dn A dt = k (T )n A (6.20) Notice the temperature dependence of k (T ) prevents us from solving this di erential equation immediately. We must solve it simultaneously with the energy balance, which provides the information WebFeb 12, 2024 · Thus if the reaction. (1) A + B → products. is first-order in both reactants so that. (2) rate = k [ A] [ B] If B is present in great excess, then the reaction will appear to be zero order in B (and first order overall). This commonly happens when B is also the solvent that the reaction occurs in. high build peel bonding primer bp-1100
