Answer: E. trigonal planar
Explanation:
The trigonal planar geometry is made up of 3 equally spaced sp2 hybrid orbitals arranged at angle 120° to each other, The molecule are electron deficient and does not follow octet rule. Therefore, a molecule containing an sp2 hybrid central atom has a trigonal planar geometry e.g boron hydride (BH3)
Answer:Rate of reaction can be determined in terms of concentration of reactants consumed or concentration of product formed per unit time
Explanation: For the reaction below
A ===>B
The reactant is A while the product given is B.
Reaction rate = Δ[B]/Δt = -Δ[A]/Δt
The concentration of A will decrease with time while the concentration of B will increases with time.
The negative sign in -Δ[A]/Δt is to convert the expression to positive since the change will always be negative (decreases)
