How does an increase in temperature generally affect the rate of a reaction??

Answer: Option (b) is the correct answer.
Explanation:
When we increase the temperature of an object then there will be increase in kinetic energy of objects. As a result, collision between the molecules will increase.
Hence, there will be increase in rate of reaction.
Also, K.E =
where k = boltzmann constant
T = temperature
So, kinetic energy is proportional to temperature. Hence, when temperature will increase the kinetic energy will also increase.
Thus, we can conclude that an increase in temperature generally affect the rate of a reaction as the rate increases.

Answer:
27.25°C
Explanation:
hello,
this question involves heat transfer in an object and to find the final temperature, we'll use formula for heat transfer
data;
mass = 12g
heat energy (Q) = 12J
initial temperature (T1) = 25°C
final temperature (T2) = x
specific heat capacity (c) = 0.444J/g°C
heat energy(Q) = mcΔt
Q = mc(T2 - T1)
the final temperature was 27.25°C
