Answer #1

answer : b. If a system is at equilibrium, the rate of the forward reaction is equal to the rate of the back reaction

explanation:

a ) this option is wrong . at equilibrium the system always in dynamic nature product converts into reactants and reactants converts into product . there ie no ceasing of the reaction at equilibrm

b) at equilibrium rate of forward reaction = rate of backward reaction

c) at equilibrium at physical properties are constant like concentration color density etc. no chaneg in the product concentration unless we apply extrnal conditions. so c ) option is also wron.
