Based on the effect of temperature on a reaction, a change in temperature affects the rate constant K.

Based on the Arrhenius equation, the y-intercept gives the value of ln A.

From the value of the slope, the value of Ea is 42.1 J/mol.

<h3>What is the effect of temperature on a reaction?</h3>

A change in the temperature of a reaction acts to increase the rate of reaction.

  • Change in temperature has no effect on the ideal gas constant.
  • Change in temperature has no effect on the activation energy.
  • Change in temperature has no effect on the concentration of reactants.
  • Change is temperature can either lower or increase the rate constant of a reaction.
  • Change in temperature has no effect on the order of reaction.

According to the Arrhenius equation, the y-intercept gives the value of ln A.

From the graph; slope = -Ea/R

Ea = -slope/R

Where;

  • Ea is activation energy
  • R is molar gas constant = 8.314 J/K.mol
  • Slope = -350 K

Ea = -(-350)/8.314

Ea = 42.1 J/mol

2. Determine the molarity of the NaOH solution in each trial. a. Trial 1 Molarity: b. Trial 2 Molarity: 3. Calculate the average
butalik [34]

Answer:

This question is incomplete

Explanation:

This question is incomplete but...

1) You can calculate the molarity of the NaOH for each trial by following the steps below.

The formula for Molarity (M) is

M = number of moles (n) ÷ volume (V)

where the unit of volume must be in Litres or dm³

The unit of molarity is mol/dm³ or mol/L or molar conc (M)

The final answer must have the unit of molarity

If the number of moles is not provided, look out for the mass of NaOH used and then calculate your number of moles (n) as

n = mass of NaOH used ÷ molar mass of NaOH

Where the atomic mass of sodium (Na) is 23, oxygen (O) is 16 and hydrogen (H) is 1. Hence, molar mass for NaOH is 23 + 16 + 1 = 40 g/mol

n = mass of NaOH used ÷ 40

2) Average Molarity will be (Trial 1 Molarity +Trial 2 Molarity) ÷ 2

Answer must be in mol/dm³ or mol/L or M

3) Label the volumentric flask containing the NaOH solution with the answer gotten from (2) above

Compare and contrast a pure substance with a mixture and give an example.
Inessa [10]

Of any substance? What about two powders such as 1/2 cup of white flour, then mixing 1/2 cup of salt together with the flour. This would then form a more coarse mixture being that the two particles differ in shape.
