This is especially important in the n-C_3H_7Br reaction for which the rate constant increases by a factor of 4 between room temperature and 230 K. Not only does the overall rate increase but also the channel-forming Br~-. 展开
<p>To solve the problem, we need to determine how the rate of a reaction changes with an increase in temperature. The problem states that the rate of reaction doubles (increases by two times) for every 10°C rise in temperature. We are asked to find the
A remains constant B depends on the substance C decreases D increases Solution Verified by Toppr The rate of reaction or speed of reaction for a reactant or product is defined as how fast or slow a reaction takes place. The rate of reaction decreases as the reaction proceeds because the con...
