Answer:
0.24 s-1
Explanation:
We first list the parameters as shown in the image attached. The variables are now properly substituted. This equation is used to calculate the rate constant and clearly show us the dependence of the rate constant on temperature. From this equation, we can clearly and easily see that the rate constant increases exponentially with increase in temperature of the reaction system.
Answer:
Ionic.
Explanation:
Elements with higher electronegativity values are better at attracting electrons in a chemical bond.
In this example, the difference between the electronegativity of oxygen and lithium is . Since
, the bond between the two elements would likely be ionic.
It is possible to reach the same conclusion based on the fact that lithium is a metal while oxygen is a nonmetal. When metal elements react with non-metal elements, the product is typically an ionic compound- with ionic bonds between the atoms.
