## Zero Order Meaning

$\frac{d[R]}{dt}=-k; [R]=-kt + [R]_{0}; t_{\frac{1}{2}}=\frac{[R]_{0}}{2k}$

### Zero Order Meaning

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

### Re: Zero Order Meaning

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?

### Re: Zero Order Meaning

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