First order reaction rate graph

WebGraphical Representation of a First-Order Reaction If the graph is linear and it has a downward slope, then the reaction must be of the first order. Half-Life of a First-Order Reaction The amount of time needed to lower the reactant concentration to 50% of its initial value is known as the half-time or half-life of a first-order reaction. WebFeb 28, 2024 · So, to calculate the rate of reaction from just a graph, Rate =− Δ[reactant] Δtime = Δ[product] Δtime = − Δ [ r e a c t a n t] Δ t i m e = Δ [ p r o d u c t] Δ t i m e. This equation ...
