hi

I need help with this question please.

1. consider the decomposition of N2O5 in carbon tetrachloride(ccl4) at 45c

2N2O5(soln)-> 4NO2(g)+ O2(g)

The reacion is first order in N2O5, with the specific rate constant 6.08*10^-4 per second.calculate the reaction rate under these condition

please can u tell me how to do this question.

Thank you.

  • chemsitry -

    rate constant= k[A]^m[B]^n is the general formula for mA+nB>C

    so here, that becomes

    r=k [N2O5]2

    k= rate/(MolarityN2O5)^2
    you need to know the concentration of the dinitrogen pentoxide.
