When an experimenter draws a conclusion that he assumes will apply to all situations set up similarly to his test situation, eve
frosja888 [35]

Before making any observations, deductive reasoning relies on the formulation of a hypothesis and its subsequent substantiation.

<h3>Deductive reasoning: What does it mean?</h3>

Since the sentence states that "he assumes will apply to all instances," he is suggesting something before to carrying out any observation, which is the foundation of deductive reasoning.

A conclusion in deductive reasoning is based on the agreement of several premises that are typically taken to be true. Sometimes, top-down logic is used to describe deductive reasoning. Making logical assumptions is the foundation of deductive reasoning, which then bases a conclusion on those assumptions.

The primary distinction between inductive and deductive thinking is that the former tries to develop a hypothesis, whilst the latter aims to test an existing theory. From specific observations, inductive reasoning proceeds to

Does the density of a gas depend on the molar mass of a gas?
amid [387]
No it doesn't. The density of a gas depends on the temperature that is found. If it's hot the density reduces since its molecules spread, while at cold temperatures the density rises.

2. Circle all of the following that change with the temperature of a reaction.
OverLord2011 [107]

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
