Answer:

-40 degress

Explanation:

To find the temperature when both are equal, we use an old algebra trick and just set ºF = ºC and solve one of the equations. So the temperature when both the Celsius and Fahrenheit scales are the same is -40 degrees.

The reaction of ethyl acetate with sodium hydroxide, CH3COOC2H5(aq)+NaOH(aq)⇌CH3COONa(aq)+C2H5OH(aq) is first order in CH3COOC2H

Ne4ueva [31]

Answer:

so the reaction rate increases by a factor 6.

Explanation:

For the given equation the reaction is first order with respect to both ester and sodium hydroxide

So we can say that the rate law is

$Rate(initial)=K[NaOH][CH_{3}COOC_{2}H_{5}]$

now as per given conditions the concentration of ester is increased by half it means that the new concentration is 1.5 times of old concentration

The concentration of NaOH is quadrupled means the new concentration is 4 times of old concentration.

The new rate law is

$Rate(final)=K[1.5XNaOH][4XCH_{3}COOC_{2}H_{5}]$

the final rate = 6 X initial rate

so the reaction rate increases by a factor 6.

A pascal is a unit for measuring pressure. Which of the following is equal to a pascal unit?

Assoli18 [71]

The pascal (pronounced pass-KAL and abbreviated Pa) is the unit of pressure or stress in the International System of Units (SI). It is named after the scientist Blaise Pascal. One pascal is equivalent to one newton (1 N) of force applied over an area of one meter squared (1 m2).
