Question

s been 3. "Scaling up” a reaction usually (a) Reduces the chance the chance for a runaway reaction because the heat capacity of the system is larger es the chance for a runaway reaction because it is (b) Reduces the chance harder to add heat to larger systems ases the chance for a runaway reaction because heat transfer occurs at surfaces and the volume-to-surface area value increases ses the chance for a runaway reaction because heat transfer occurs at surfaces and the volume-to-surface areal value decreases

Answer 1

When the reaction is scaled up, the runaway reaction is more likely to occur if proper precautions are not taken. The volume of the reaction increases when the reaction is scaled up but the surface area does not increase proportionately to the increase in the volume of the reaction. Thus, the volume to surface area increase. This reduces the capacity of the system to transfer heat when the reaction is scaled up.

Correct answer is option C.

Based on the above understanding, option D can be ruled out ( volume to surface area does not decrease).

Though the heat capacity of the system has increased, the amount of the reactants that can lead to runaway reaction have also increased. So the option A will not be correct

The runaway reaction will generate its own heat. So even if it is harder to heat the system, the reaction will still be runaway. So obtion B can also be ruled out.
