In this example problem, we calculate the instantaneous rate of reaction and the rate of change in concentration for both reactants and … NettetAn instantaneous rate is a differential rate: -d[reactant]/dt or d[product]/dt. We determine an instantaneous rate at time t: by calculating the negative of the slope of the curve of …

Nettet1. des. 2024 · Hence, Rate of reaction at a given time = gradient of the curve at that instant. The rate of reaction at a given time, t, can be calculated through the following steps. Step 1: Draw a tangent (line AB) on the curve at the time t. Step 2: Draw the right-angled triangle ABC. NettetRearranging the rate equation, the value of the rate constant ‘k’ is given by: k = Rate/ [A] x [B] y. Therefore, the units of k (assuming that concentration is represented in mol L -1 or M and time is represented in seconds) can be calculated via the following equation. k = (M s-1)* (M-n) = M(1-n) s-1. The units of the rate constants for ... picaridin off
