The rate constant for the decomposition reaction of H2O2 is 3.66 × 10−3 s−1 at a particular temperature. What is the concentration of H2O2 in a solution that was initially 10.0 M H2O2 after 15.0 minutes have passed?

 3.72 M

Explanation:

Expression for rate law for first order kinetics is given by:

where,

k = rate constant =

t = age of sample = 15.0 minutes

a = let initial amount of the reactant  = 10.0 M

a - x = amount left after decay process = ?

The concentration of in a solution after 15.0 minutes have passed is 3.72 M

explanation:

covalent bonds

consist of pairs of electrons shared by two atoms, and bind the atoms to fixed orientation and requre high energies to break them

ionic bonds

when two atoms differ considerably in their electronegativity, then one of the atoms will lose its electron to the other atom. this results in a positively charged ion(cation) and a negatively charged ion (anion)
