rate=k[A]x[B]y[C]z


where:

rate = initial rate

k = rate constant

[A], [B], [C] = reactant concentration

x, y, z = reaction order



Calculate the order of the reaction with respect to A.

Look for the data where the concentration of A changes while the concentration of B and C remains the same.
