the rate would be four times larger. apex
The rate would be one-fourth. Correct on Apex.

Without phenol, the bromine would not have a stable medium for the reaction, leading to a lack of suitable environment for the reaction to occur. Phenol acts as a catalyst in this reaction by providing a stable medium for the formation of the bromine products.
If you add iron to a solution of magnesium sulfate, a displacement reaction would occur, where the iron would displace the magnesium in the sulfate compound. This would result in the formation of iron sulfate and magnesium metal.
If the concentration of NO is halved, the rate of the reaction will also be halved. This is because the rate of the reaction is directly proportional to the concentration of NO raised to the power of its coefficient in the rate law (in this case 1). So, halving the concentration of NO will result in a proportional decrease in the rate of the reaction.
The rate would quadruple (increase by a factor of 4). This is because the rate depends on the SQUARE of the concentration of NO.

If the concentration of NO was doubled in the rate law rate = k[NO]2[H3], the rate of the reaction would increase by a factor of 4. This is because the rate of a reaction typically increases with an increase in the concentration of reactants, raised to a power dictated by their respective coefficients in the rate law equation.
In the given rate law, the rate of the reaction is dependent on the concentration of NO and possibly other reactants. If the concentration of NO is halved, the rate of the reaction would decrease proportionally, assuming that NO is a reactant in the rate law. Specifically, if the rate law is of the form rate = k[NO]^n[other species], the rate would be affected by the new concentration of NO, resulting in a reduced reaction rate. The exact impact on the rate would depend on the order of the reaction with respect to NO.
The rate would be one-fourth. Correct on Apex.
If both dimensions are doubled then the area is quadrupled. This is true of any geometric shape.
They would create a double greenhouse effect
The volume would increase by a factor of 23 = 8
