When the reaction begins, the researcher records that the rate of reaction is such that 1 mole of a is consumed per minute. after making changes to the reaction, the researcher notes that 2 moles of a are consumed per minute. what change could the researcher have made to effect this change?

a. utilize reaction conditions to convert both reactants to solids.
b. decrease the concentration of reactant b to allow c to be produced at a greater rate.
c. increase the temperature, allowing more frequent collisions of a and b with greater kinetic energy.
d. increase the concentration of c to allow for more frequent collisions of a and b of higher energy
e. introduce a catalyst to decrease the consumption of a and b.

C. Increase the temperature, allowing more frequent collisions of A and B with greater kinetic energy.

Explanation:

For the reaction:

A + B → 2C

You can increase the consume of A:

A. Utilize reaction conditions to convert both reactants to solids. FALSE. Convert both reactants in solids makes less frequent collisions doing difficult the reaction.

B. Decrease the concentration of reactant B to allow C to be produced at a greater rate. FALSE. The decreasing of B will make the reaction slowly.

C. Increase the temperature, allowing more frequent collisions of A and B with greater kinetic energy. TRUE. The increase of temperature will make more frequent collisions of A and B doing the reaction faster.

D. Increase the concentration of C to allow for more frequent collisions of A and B of higher energy . FALSE. The increase of C makes less frequent collisions doing difficult the reaction.

E. Introduce a catalyst to decrease the consumption of A and B. FALSE. Introducing a catalyst increase the consumption of A and B.

This is what i found “nuclear fuel is material used in nuclear power stations to produce heat to power turbines. heat is created when nuclear fuel undergoes nuclear fission. most nuclear fuels contain heavy fissile actinide elements that are capable of undergoing and sustaining nuclear fission.” i hope this you for what your looking for. can you plz mark me brainliest?

Answer from: Quest

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6

What is the typical rotational frequency frot for a molecule like n2 at room temperature (25∘c)? assume that d for this molecule is 1å=10−10m. take the total mass of an n2 molecule to be mn2=4.65×10−26kg. you will need to account for rotations around two axes (not just one) to find the correct frequency. express frot numerically in hertz, to three significant figures.
