Chemistry the rate of reactions

[taylorswift08]

Under experimental conditions, at a temperature of 320°C, one mole of NOBr decomposes according to the reaction NOBr= NO +1/2 Br₂. The coefficients before the formulas of the substances in the reaction are simultaneously the values ​​of powers of their concentrations. Calculate how many moles of NOBr are left unreacted if it is heated for 5 hours and the rate constant is 2.2* 10^-5 mol^¹* s^-1

[ChenBeier]

Calculate the moles consumed = time × K

We have 1 mol NOBr - consumed moles = moles left

[taylorswift08]

is the moles consumed = time × K a formula that is givven in school or?

[ChenBeier]

In the exercise K 2.2* 10^-5 mol^¹* s^-1 and time 5 h is given.


But probably has to use Arrhenius equation

A(t) = A0* exp(-kt)
