If I had the equation
H2 + I2 > 2HI
could I write the rate of reaction as
d[H2 + I2]/dt = k[H2]^x[I2]^y
were x is the order of reaction with respect to x and y is just the order of reaction with respect to y
thanks

Kate,
well i guess I need the negative sense it's the reactant
d[H2 + I2]/dt = k[H2]^x[I2]^y
is this correct?
