Choose the incorrect statement a) The haft-life time of the first order reaction does not depend on the concentration of reactant
b) The reaction rate is affected by the temperature, concentration, and nature of reactants
c) The higher the activation energy, the quicker the reaction rate
d) The haft-life time of the second order reaction is influenced by the initial concentration of
reactants

since electrons are negative the answer is neagtaive

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
