Answer:
Li2O is the molecular formula for lithium oxide.
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:
Gas is different from liquid. Liquid has a definite volume but takes the shape of the container it is in. Gas on the other hand, has no definite shape or volume.
