CHM LECTURE NOTES13.2Rate of Reactions:Rate of a Reaction = change in concentration of a component/ interval of timeH2 + I2 2HIRate = Δ [H2]/ Δt (ΔH2 = [H2]f – [H2]i and Δt= change in time)Rate = - Δ [I2] / Δt(the negative sign in this one is because the concentration of I2 decreases with time)Rate= ½ Δ[HI]/ Δt (the ½ is because you multiply the rate by the reciprocal of the stoichiometric coefficient of the reaction component) Average rate of a reaction: plug in values for the change in concentration (final – initial) time (final – initial) into the rate equation, same as aboveInstantaneous rate of reaction: rate at a particular moment in time*On a graph, the slope of the tangent will give you the instantaneous rate of
