Zero Order Meaning

Postby AngelaLin_1D » Sat Feb 13, 2016 10:10 pm

If the reaction is a zero order, and the rate of reaction is independent, how come a slope still exists for the straight line?

for zero order, Rate=k so plotting the concentration vs time gives a constant slope, ie. straight line

Basically, what its saying, is the CHANGE of the concentration of the reactant/reactants doesn't have an affect on the line.

Rate of zero-order rxn = k

Note that what we're plotting in zero-order reaction is Concentration of R vs Time, which yields a straight line with slope of m, represented by k. The reaction is independent of initial condition, so [R]-reactant concentration of that specific rxn will decrease at a constant rate of k despite initial [R] given.

Will a zero order reaction mean that changing the concentrations will result in no change?

Rate is equal to k in a zero order reaction, and therefore plotting the points creates a straight line
