Given the balanced equation for the decomposition of INO, and the rate of disappearance of INO, write the expressions for the rates of appearance of I2 and NO

Question

2INO(g) ---> I2(g) + 2NO(g)

Reactant: Product(I2): Product(NO):
-∆[INO]/2∆t = ??/?? = ??/??

Answer 1

I can't make the delta sign so delta t = dt.
-d[INO]/2dt = d[I2]/dt = d[NO]/2dt
