Consider the reaction NOBr(g) => NO(g) + 1/2 Br2(g). A plot of 1/[NOBr] vs time give a straight line with a slope of 2.00 M-1
timama [110]

Answer:

Thus, the order of the reaction is 2.

The rate constant of the graph which is :- 2.00 M⁻¹s⁻¹

Explanation:

The kinetics of a reaction can be known graphically by plotting the concentration vs time experimental data on a sheet of graph.

The concentration vs time graph of zero order reactions is linear with negative slope.

The concentration vs time graph for a first order reactions is a exponential curve.  For first order kinetics the graph between the natural logarithm of the concentration vs time comes out to be a straight graph with negative slope.

The concentration vs time graph for a second order reaction is a hyberbolic curve. Also, for second order kinetics the graph between the reciprocal of the concentration vs time comes out to be a straight graph with positive slope.

Considering the question,

A plot of 1/[NOBr] vs time give a straight line with a slope of 2.00 M⁻¹s⁻¹.

<u>Thus, the order of the reaction is 2.</u>

<u>Also, slope is the rate constant of the graph which is :- 2.00 M⁻¹s⁻¹</u>

If a gas is cooled from 343.0 K to 283.15 K and the volume is kept constant what final pressure would result if the original pre
mario62 [17]

Answer:

627.4 mmHg

Explanation:

From Gay-Lussac law:

\frac{p1}{t1}  =  \frac{p2}{t2}

p1 = 760 mmHg

t1 = 343 K

t2=283.15 K

p2 = p1 \times  \frac{t2}{t1}

p2 = 760 \times  \frac{283.15}{343.0}

p2 = 627.4 \: mmhg
