For metals (lithium) reactivity increases down a group and from right to left across a period. So lithium is not that reactive. I think ♀️
Answer:
Explanation:
Using integrated rate law for first order kinetics as:
Where,
is the concentration at time t
is the initial concentration
Given:
75 % is decomposed which means that 0.75 of
is decomposed. So,
= 1 - 0.75 = 0.25
t = 60 min
k = 0.023 min⁻¹
Considering the expression for half life as:-
Where, k is rate constant
So,
Answer:buckled railroad tracks on a hot day
