Adding an inhibitor to a chemical reaction will have which of the following effects on a reaction?

Chemistry
1 answer:
Levart [38]3 years ago
7 0

Answer: a. the inhibitor will decrease the rate of reaction.

Explanation: The rate of the reaction is affected by addition of inhibitors which are also called as negative catalysts as they decrease the rate of reaction unlike catalysts which enhance the rate of reaction.

Inhibitors delay, slow or prevent the chemical reactions by binding with the substrate or the catalyst and hence prevent them to function normally.

How many grams of carbon dioxide are in 88.5 L at STP?
34kurt

Answer:

173.8g

Explanation:

STP means standard temperature and pressure

The temperature there is 273k while the pressure is 1 atm

now we are to use the ideal gas equation to get the number of moles first

Mathematically;

PV = nRT

here P = 1 atm

V = 88.5 L

n = ?

R = molar gas constant = 0.082 L atm mol^-1 K^-1

Now rewriting the equation we can have

n = PV/RT

plugging the values we have

n = (1 * 88.5)/(0.082 * 273)

n = 88.5/22.386

n = 3.95 moles

Now we proceed to get the mass

Mathematically;

mass = no of moles * molar mass

molar mass of carbon iv oxide is 44g/mol

mass = 3.95 * 44 = 173.8 g

Which of the following do/does not change with the change in temperature?
Phantasy [73]

Answer:

c. Both i & ii

Explanation:

Moles do not change with temperature hence Mole fraction does not depends of temperature.

Molality is number of moles of solutes per kilogram of solvent. It has no relationship with temperature.

This means both of them do not change wit the change in temperature.

Correct option;

c. Both i & ii
