A 10-volt power supply is used to power a circuit, producing a current of 2 A. If the total resistance of the circuit is doubled, how will this affect the circuit? A. The current will change so that the voltage drop for a complete loop through the circuit remains at 10 V.
B. The voltage drops across each resistor will be unaffected because each will remain at 0 V.
C. The current will change so that the voltage drop for a complete loop through the circuit becomes 5 V.
D. The voltage drops across each resistor will all double to match the change in resistance.

In the derivation of rrkm theory, a factor of 1/2 is introduced when equalizing the rates of formation and decomposition of activated complex as keal-hr) = ko this is clearly against the assumption of transition state theory that states all the activated complex in the transition state iss going to the product. find the reason why this factor is introduced here.
