ermic.Table: Temp (K) K(c)300. 1.5 x 10^4600 55900. 3.4 x 10^-3.a) True b) False"This would be true because as we are increasing T, the K value is decreasing, which indicates that we are favoring the reactants; therefore, heat is a product, which means it is exothermic.
The reaction as shown is known to be an exothermic reaction.
<h2>Endothermic and exothermic reaction:</h2>
Depending on the temperature of the reaction vessel after reaction, the reaction could be classified as;
Endothermic
Exothermic
In an endothermic reaction, heat is absorbed and the rate of reaction increasing with increase in temperature while in an exothermic reaction, the rate of reaction decreases with increase in temperature.
Hence, the correct statements are;
The reaction is an exothermic reaction.
The value of K decreases as the value of T increases.
A force can speed up or slow down an object. A force can change the direction in which an object is moving. A bigger force on an object will produce a bigger change in the motion. A heavier object requires a larger force than a lighter object in order to undergo the same change in motion.
