Answer:
Slope = M / s
k = +0.016 / s
Explanation:
Given:
- A first order reaction ---- (missing from question)
- Slope is -0.016
Find:
Units of Slope and value of k
Solution:
- The slope of the concentration time graph is called the rate of reaction. For which the rate of reactions is always expressed as change in concentration of reactants per unit time. Hence,
Slope = Change in concentration / time
Slope = M / s
- The units of k constant depends on the order of reaction. The graph given is of first order. Hence, the sum of moles of reactants and products is the same. Hence, the units of constant k is given by:
k = +0.016 / s
Answer:
the movement of snail on the ground is in random motion.
the strings of the guitar is in oscillatory motion.
the whirling of stone tied with a thread is in circular motion.
Hypothesis: The water will squirt far.
Indep.V.: Height of hole.
Depend.V.: Range of squirt
Constant: Everything that isnt the independant var. such as filled liquid.
Control: None,I believe.
Number of groups: 4
Trials per group: 4

<h3># Question </h3>
Q1- the speed will increase because the particles will have more energy which causes them to move faster
Explanation:
<h3>With an increase in temperature, the particles gain kinetic energy and move faster. The actual average speed of the particles depends on their mass as well as the temperature – heavier particles move more slowly than lighter ones at the same temperature. </h3>
