How much energy is required to raise the temperature of 3 kg of iron from 20C to 25C

1935 J

How can the rate constant be determined from the rate law

The rate constant is the reaction rate divided by the concentration terms.

Which of the following conclusions can be drawn from the curves in the energy diagram

. The reaction represented by curve B will go faster than the curve A reaction.

What information does Gibbs free energy give about a reaction

It tells if the reaction will process spontaneously or not

What would happen to the rate of a reaction with rate law kNO2H2 if the concentration of NO were doubled

the rate would be four times larger. apex

What is the rate constant of a reaction if rate 1 10-2 molLs A is 2 M B is 3 M m 2 and n 1

4.5 (moI/L)/s -apex

How does the entropy change in the reaction 2c3h6g 9o2g 6co2g 6h2og

The entropy increases

What happens to the reaction rate when a catalyst is used in a chemical reaction

With a catalyst the reaction rate is higher.

Which of the following best describes a bronsted lowry acid base reaction

Acid + Base = Salt+Water (APEX)

How is the delta H fusion used to calculate volume of liquid

It is not. The density and mass would be used to find the volume.

What phase has the lowest entropy

solid-apex

What is a reaction rate apex

how slow or fast A reaction progresses - apex

Would form a spontaneous reaction at 298k

Not B

How is the effect of concentration changes on the reaction seen in the rate law

Reaction rate increase when the concentration increase.
