WebThe initial rate is the instantaneous rate at the start of a reaction when the time, t is zero (t = 0). The initial rate can be found by measuring the gradient of a tangent drawn at t = 0 on a concentration−time graph. A clock reaction is a more convenient way of obtaining the initial rate of a reaction by taking a single measurement. chisel and bits for minecraft pocket edition
