NaBH4 is typically used in excess. Since the rate law for reduction of an aldehyde is first order in both NaBH4 and in aldehyde, how will using excess NaBH4 affect the overall reaction rate

As the amount of NaBH4 is increased, the overall reaction rate also increases
Explanation:
This question tells us that NaBH4 is typically used in excess.
the rate law for reduction of an aldehyde is first order in NaBH4 and also in aldehyde,
We have The rate of reaction to be the equation below;
Rate = k[aldehyde][NaBH4]
The Rate of the reaction is directly proportional to NaBH4 concentration.
Therefore since they are directly proportional, when the amount of NaBH4 is increased, we will also have the overall reaction rate increase.
