Question

What is the concentration of N2O5 at 270 s in the given reaction with a rate constant of 7.81x10⁻3 M/s?

a) 0.165 M
b) 0.136 M
c) 0.112 M
d) 0.092 M

Answer 1

The question requires more information to calculate the concentration of N2O5 at 270 seconds, such as the initial concentration and the reaction order since the provided rate constant suggests a reaction that is not first-order.

Step-by-step explanation:

The question asks to calculate the concentration of N2O5 at 270 seconds in a reaction with a known rate constant. To provide an accurate answer, the question would ideally include the initial concentration of N2O5 and the order of the reaction because the rate constant units suggest that it is not a first-order reaction. However, with the given information, it is not possible to calculate the concentration of N2O5 at 270 seconds.

Without the initial concentration and reaction order, it's akin to solving an equation with two unknowns. Based on the data provided for other parts of the question, it appears that additional information might have been given in the original problem that is not present here, which can make the calculation feasible.
