**Chemical Reaction of Nitrogen Dioxide**In this example, nitrogen dioxide (NO₂) reacts to form nitrogen monoxide (NO) and oxygen gas (O₂). The chemical equation representing the reaction is:\[ 2NO_2(g) \rightarrow 2NO(g) + O_2(g) \]**Problem Statement:**A reaction container starts with an initial concentration of nitrogen dioxide, NO₂(g), at 0.350 M (molarity). The task is to determine the concentration of NO₂(g) after the reaction has proceeded for 30 seconds, given that the rate of NO₂(g) loss is \(1.20 \times 10^{-3}\) M/s.**Calculation Summary:**Given:- Initial concentration of NO₂(g): 0.350 M- Rate of reaction: \(1.20 \times 10^{-3}\) M/s- Reaction time: 30 secondsThe rate of reaction indicates how fast NO₂ is being consumed. To find the concentration after 30 seconds:\[ \text{Change in concentration} = \text{Rate} \times \text{Time} = 1.20 \times 10^{-3} \times 30 \]\[ \text{Change in concentration} = 0.036 \, \text{M} \]Subtract this change from the initial concentration to get the final concentration:\[ \text{Final concentration of NO}_2(g) = 0.350 \, \text{M} - 0.036 \, \text{M} = 0.314 \, \text{M} \]The concentration of NO₂(g) after 30 seconds is 0.314 M. This example demonstrates the calculation of reaction kinetics for a given chemical process.

Change in the concentration of compound per unit time is known as rate of a reaction.

Can you help me correcting this questions in the picture with the notes below please? Notes: In question 1a, the rate law is fine but should have partial pressures, not concentrations. In 1b, the units of the answer are incorrect; they should have "atm" in it. Hint: in the denominator of the calculation is atm^3.

Peroxynitric acid (HOONO2) is an unstable molecule that decomposes to nitric acid and oxygen: 2HOONO2(aq) → 2HNO3(aq) + O2(g)When the concentration of peroxynitic acid is graphed against time, the resulting plot is curved, but if the logarithm of this concentration is plotted, we instead get a straight line. Based on this, which statement is true? a) This decay is a second order in peroxynitric acid. b) The slope of the straight-line graph is the rate constant. c) One needs the concentration of peroxynitric acid to calculate its half-life. d) The rate law appears to be of the form -Δ[HOONO2]/Δt = k[HOONO2].
